Oud or lute?

Dr. Oud - 6-22-2007 at 08:46 AM

My latest acquision is an unusual oud, which was played as a lute with tied on frets. The body is unusally long - 22 3/8 in (568mm); narrow - 12 3/4 in (323mm); and deep - 8 in (203mm). The neck is only 7 11/16 long (297mm) which would make a string length of 23in (586mm) but this is not in proportion to the body length. The top ribs are missing on both sides, so there's no clue to where the braces or bridge was placed?!?

1889 ...

Wow .. !

How did you come about this find, Doc?

Dr. Oud - 6-22-2007 at 10:28 AM

I bartered it for some restoration work for Ronny Andersson.

Faladel - 6-22-2007 at 11:35 AM

Basel Altounjy is a very ancient luthier of my city, the family altounjy exists in aleppo and it is near to my family, there is a very well preserved oud of Basel that I have played .

Hey doc

if i am not mistakin gmy uncle has a oud liek this in london, which is funny bc it hink he has a face of a oud liek this i dught this only but i knwo its frm the 20 or 30s and the body broke in many areas so he said when i come down to visit him in london when i get a chance he might give it to me then
but it looks alieka awesome oud to me
thx sammy

Ronny Andersson - 6-24-2007 at 01:18 PM

well this is the closest an oud player can come Laux Malers baslutes

Jameel - 6-24-2007 at 08:44 PM

Nice one Doc.

Reminds me of the oud in this photo from Joe Tawadros' website. The one on the far left.

Incidentally, I was talking once with kanun player Dr. George Sawa about old ouds. He said that all the old ouds before the turn of the 20th century had this shape. The wider, bigger ouds are relatively new.


jdowning - 6-25-2007 at 08:56 AM

Interesting. It is, of course an oud but Ronny Andersson's observation about the similarity to lutes by Laux Maler prompted me to check data that I have on file relating to Maler lutes.
Laux Maler was a famed German luthier operating during the first half of the 16th C. None of his lutes survive in their original state as they have all been subject to modification over the centuries - fitted with wider necks and bridges to carry a larger number of strings. The surviving instruments all have a characteristic long narrow almond shaped body profile built up with from 9 or 11 ribs.
Some years ago - using dimensional data from the surviving Maler instruments - I made a reconstruction of what I thought these lutes may have looked like originally. The design and barring of the belly was based on an original belly fragment in the Germanisches Nationalmuseum, Nuremburg - Cat. No. M154. This belly has traces of the original bridge set low down below the current bridge location. The reconstructed lute with this low bridge position and neck carrying eight frets to the body joint gave a string length of 730mm. The lute has been quite successful and I still use it today.
Taking a tracing of the oud body profile from the image posted by the Doc and superimposing this over the reconstructed Maler lute profile - to the same scale - it can be seen that the profiles are very similar as are the ratios of body length to body width which come to 1.75 for the Maler and 1.76 for the oud. I have assumed that the centre of the label is the location of the oud soundhole.
The big difference is in the body depth. Maler lutes had a more or less semicircular body profile whereas as the oud is proportionally deeper in section. This deeper body profile, however, can be found on lutes of the late 17th/early 18th C by makers such as Hoffman and Tielke (who also used a narrow body profile similar to the Maler lutes).

Ronny Andersson - 7-1-2007 at 08:38 AM

Indeed interesting about the Maler lutes John. I believe this oud had a soundboard made of Lebanon cedar and I know Richard will use cedar for an eventually reconstruction of the soundboard.
Here are some photos of Richard's monster, compare its size next to a Turkish oud!



Ronny Andersson - 7-1-2007 at 08:47 AM

Here some interesting pictures of a recent reconstruction of an early lute based on iconographic sources circa 1426. It is built and reconstructed by David Van Edwards; string length 67cm!


jdowning - 7-2-2007 at 05:27 AM

I may get a more accurate profile of the oud from the image Ronny posted as there could be some foreshortening in Richard's photo. So will recheck the comparison with the Maler reconstruction and see how it turns out a second time around.
The thin end plate of the oud is similar to that on the old oud that I am restoring. This type of end plate was used on lutes also except that they were usually not so deep and extended further around the bottom section of the body. There seems to be a hole in the neck block but no sign of a dowel or dovetail? Could this be an old nail hole originally used to secure the neck to the body (in addition to a glued butt joint) - a practice followed by early lute makers - or is it just that the neck joint does not pass through the neck block on this instrument and is, therefore, not clearly visible in the photo?
Nice fingerboard inlay - could you post a more detailed image of that as well for information? Thanks.
John

Ronny Andersson - 7-2-2007 at 09:34 AM

Yes John, I noticed the same when I had the oud here that the neck is attached to the neck block with what seems to be a nail- let's wait for Richard...



jdowning - 11-26-2007 at 10:41 AM

Richard - is it possible that the neck of this instrument has been cut down - ie reduced in length - some time in the past? I am curious having just carried out a preliminary comparison of three 'early' oud profiles in "Question - Big Ouds, Little Ouds" in the "Advice, Tips and questions" Forum and noticing that the neck seems to be proportionally shorter those of the other two ouds.

jdowning - 11-28-2007 at 03:20 PM

On the other hand the neck length is very close to 1/4 of the total length of the oud - which is the proportion that manuscripts from the 10th to 14th C (for example Ikwan al-Safa and Kanz al-tuhaf) say it should be. Is it possible that ouds - even into the late
19th C - were still being built in accordance with these ancient traditions but which, in the short space of time of the last 150 years or so, are now lost?

Dr. Oud - 11-29-2007 at 09:31 AM

The neck joint indicates no forshortening of the neck, so I'm inclined to agree with the 1/4 length proportion. I would welcome any information about bridge placement, bracing, etc of these old manuscripts, since the face and top ribs are missing.

jdowning - 11-30-2007 at 10:23 AM

Recreation of early lutes is bad enough but the situation seems to be far worse for ouds as there is apparently little data surviving either in manuscripts or extant instruments.
I can only work with secondary source material as I cannot read Arabic and so data that may be available in original manuscripts is inaccessible to me. The two early sources already mentioned in this forum - the Persian Kanz al-Tuhaf and Arabic Ibn al-Tahhan ouds - give dimensions that are suspect due possibly to scribal error. However, making a guess at what may have been originally intended, the former oud would have measured 81 cm overall length, string length 67.5 cm, body length 60.75 cm and bridge (front?) at 13.5 cm from the bottom of the body. The latter oud measures correspondingly 90 cm overall, string length 81 cm, body length 60.75 cm, and bridge (front?) 9 cm from the bottom of the body. Note that the the Ibn al-Tahhan neck is proportionally longer than 1/4 of the overall length so that the proportional bridge placement of the Kanz al-Tuhaf oud at 22% of the body length might be a more representative choice giving a string length of about 740 mm for your oud - but, of course - without further data points this is just speculation based on 14th C oud design. A late 19th C oud may have had a higher bridge position than this with consequent reduction in string length?
Barring is a problem with no historical data available at this point in time. As there are similarities between modern oud and early lute barring (where there is some data), the latter might be used as a guide.
For information, my recreation of the Maler lute based on the early 16th C soundboard fragment by that maker - Cat. M1.54, in the Germanisches Nationalmuseum, Nurnberg - has bar centreline placements measured from the bottom of the bowl as follows:
No below bridge bar due to the low bridge position at 65 mm, bar1 at 125 mm, bar 2 at 160 mm, bar 3 at 225 mm, bar 4 at 252 mm, a bar through the rose centre at 285 mm, bar 5 at 345 mm and bar 6, midway between bar 5 and the neck block at 410 mm.

ALAMI - 11-30-2007 at 12:42 PM

Now that the full text of "Rasael Ikhwan Al Safa" (Epistles of the Brethren of Purity.) is available as pdf (arabic) I was able to do a search on the word oud. I found the part they are talking about oud. The text says beautiful things about oud and its mystic value and symbolism, the technical part is very short.
It is partly translated in David Parfitt site:
http://www.oud.eclipse.co.uk/history.html

From what I understood the oud they're talking about is 4 course (associated with the 4 elements) and it seems to be a fretted instrument, they explain how to tie frets (they are using a word I am not familiar with : Dostaan or Doostaan (is it fret ?). however it may be the original name of "Doozan" which means nowadays "tuning"
I saved the few (arabic) pages about oud as a separate pdf that I am attaching.

On the other hand, I have a late 19th century oud (1892), it is more like modern ouds except for string length
Total length: 72 cm
String length : 63 cm
Depth : 20
Neck :21.50

Peyman - 11-30-2007 at 12:58 PM

Dastan is persian for finger positions and sometimes frets (it literally means "Hands"); and duzen is Turkish for tuning.

jdowning - 11-30-2007 at 05:26 PM

Farmer in his paper "Was the Arabian and Persian Lute Fretted" confirms that many early writers such as Al-Kindi and Al-Farabi referred to 'dasatin' or 'dastan' which were tied frets, certain evidence that the oud in the Middle Ages was fretted.
Ibn al-Tahhan did not need frets - according to Farmer - because he knew the place of every note on the fingerboard without 'dasatin'. Ibn al-Tahhan also recommended using graduated frets ie fret diameter reducing from the nut towards the bridge - common practice among lute players - and that four rolls of gut were required to fret an oud.

jdowning - 12-1-2007 at 05:31 AM

ALAMI - could you post the body length and width of your oud for information
Thanks

ALAMI - 12-1-2007 at 07:01 AM

Made in Tripoli Lebanon 1892 by Al Arja Brothers (Couldn't find any info on the makers)

5 course
Total Length: 72
String Length: 63
Body Length: 51
Body Width: 36
Depth: 20
Hole: 12 (centered at 30 cm from bottom)
nut: 3.5
Bridge: 10 cm (7.5 cm fm bottom)

jdowning - 12-1-2007 at 01:31 PM

A beautiful oud ALAMI.
Could you please confirm the measured distance from the bridge to the bottom of the bowl? I have scaled dimensions from the image but the bridge location doesn't seem to fit - 7.5 cm seems to be the distance from the back of the bridge not from the front (the side closest to the rose)? Scaling the front edge to the bottom of the bowl seems to be about
8.7 cm.
I always assume that bridge location given by early writers is from the front edge of the bridge but it might also be the centre of area of the bridge (which could approximate to the bottom face of the bridge on an oud).
Interesting that the bottom of the bowl is almost semicircular as this may be an early oud feature.
The design of the outer area of the rose does not seem to be symmetrical. Does it contain any calligraphic information about the instrument or maker etc, interwoven in the design?

ALAMI - 12-1-2007 at 02:00 PM

You're right : 7.5 is the distance from bottom to the back edge of the bridge.
The exact distance from the bottom to the bridge (inner side of the string loops) is 8.8.
What is written on the rosette is still a mystery, it is meaningless in arabic, I checked with an old calligrapher, could be old turkish.

Peyman, thanks for the clarifications on the word dastan.
While reseaarching the word I found this site:

Thanks Alami. If you post a picture of the writing I am sure someone can tell you if it's Turkish or not. The rosetter and the fingerboard look awsome.

excentrik - 12-1-2007 at 04:04 PM

wow, doc-

I cant wait to see that oud restored- what beautiful work the original maker did- thank God the label is still intact.

jdowning - 12-2-2007 at 07:46 AM

This is interesting. The profile of ALAMI's Al Arja oud looked familiar so I checked the geometry against the famous lute construction given by Henri Arnault de Zwolle in his manuscript dated around 1450 (Images of the Arnault lute have been posted several times in the past on this forum so I will not include an image again here. A full translation from the original Latin text to English is provided in an article " A Fifteenth Century Lute Design" by Ian Harwood published in the Lute Society Journal #11, in 1960).

The Arnault construction does not provide absolute measurements but gives proportional dimensions. A tracing of the image of the Al Arja oud posted by ALAMI was made and the Arnault construction overlaid on this outline for comparison. Given that there is some slight fore- shortening or possible
"barrel" distortion of the image, it was found that the oud matched the Arnault geometry remarkably closely.
The attached image shows the construction.
The bottom of the bowl is a semicircle of radius AB which is half the maximum width of the soundboard which equals the radius CD which, in turn, defines the profile of the upper part of the soundboard. The difference in my construction is that I chose a point a little above the widest part of the belly from which to scribe the radius CD which makes the Al Arja oud bowl a little longer proportionally than the Arnault lute. The front edge of the bridge is located at 1/6 of the length of the bowl (HJ) from the bottom edge to the neck joint (HK) - exactly as given by Arnault. The centre of the rose F is mid way between the front edge of the bridge and neck joint EG - as given by Arnault.
The diameter of the rose should be 1/3 the distance across the belly through the centre of the rose. On the Al Arja oud the rose diameter is 1/3 the maximum width of the belly CD.
The depth of the bowl according to Arnault should be half the width of the belly AB which means that lute has a semicircular section whereas the oud is a bit deeper in section. Also the neck length described by Arnault is much longer which is an unresolved dimensional anomaly even for lutes.
The Arnault lute has only three braces - one each side of the rose with a third bar placed between the rose and bridge (as well as a heavy end block measuring 1/3 the distance between the bottom of the bowl to bridge in thickness) - an arrangement that Ian Harwood considered would favour the lower harmonics providing a full rich tone quite different from lutes of a later time period.
The barring arrangement of the Al Arja oud would be of great interest. Is there any way to determine this non destructively - perhaps by lightly tapping the soundboard and listening for a change in pitch at the bar positions?

jdowning - 12-2-2007 at 08:08 AM

See also the close similarity to the early lute profiles posted on page 1 of "Designing a Golden Mean Based Oud"

ALAMI - 12-2-2007 at 09:21 AM

WOW, amazing !
The funny thing is that I am trying to design a golden mean based oud not realising that I already have a 115 year old one.

What I haven't yet told about this oud is that it has been already restored twice, in fact in 2 steps by Fadi Matta, the first restoration was to negate all the previous bad restorations and to set the neck. at the end of the first restoration the oud looked beaytiful, the action great, but it was still not playable, it was buzzing, Fadi asked me to wait a couple of months, but it didn't go.
The next step was a painful decision: the inlays on the fingerboard were sanded and used over the years they became very thin and "erased" in some places, the rest of the fingerboard was so "mounts and valleys" that it couldn't be fixed.
To make it playable again there was no other solution than replacing the top of the fingerboard, now the inlays are gone.
But not permanently as before taking them away I did a high resolution scan and did an exact tracing of the inlays.
The 3rd step would be to send the files to Jameel and ask him to make a new fingerboard top with a perfect replica of the original inlays.
Would you be able to do it soon Jameel ?

What I would like to add regarding this oud is that it has a deep beautiful sound, it is the oud I play most. It is stringed with Pyramid special low tension, a great set fixed by Jameel.

Lately it was played by Omar Bashir, he played it for 4 hours and fell in love with the oud, he wanted to buy it (and of course it is not for sale) but I told him that he can play it as long as he wants while he is in Beirut.

Regarding the barring: is it possible to use X-Ray or MRI or some medical device to see inside ? I may be able to do it.

I know, I have to post a sound file soon, but I would like to give the old guy a decent studio recording.

jdowning - 12-2-2007 at 10:54 AM

Thanks for the additional information Alami. Great that the oud is still being played and sounds well. I don't suppose that the previous restoration work changed the profile of the instrument? Don't wear it out though!!

X-ray technology has been used in the past to determine lute barring - although the images can show some distortion on a 3D object - so need careful interpretation to ensure accuracy. Nevertheless, a plan view as well as side view X-ray would be very useful if you can arrange it. MRI images would also be interesting if there is not a high patient demand for the machine - but I am not sure if they would have much advantage over X-ray?.
I wonder if a low cost, electronic, hand held, "stud" finder (that detects density variations (not nails) in wood - used by carpenters to locate wall timbers) would be sensitive enough to work?
Richard and Jameel no doubt will have some experience to share.

ALAMI - 12-2-2007 at 12:44 PM

John you're right !
A quick and rough superposition with the manuscript (as posted by Ronny Anderson)

What are the possible conclusions ?
An oud made in Tripoli - Lebanon in 1892 is "according" to De Zwolle manuscript 1450, pure coincidence ? or shared ancient ways ?

ALAMI - 12-2-2007 at 12:52 PM

What is written on the rosette was never identified.
It doesn't seem to be in Arabic, but the makers are arabs.
Lebanon was under the reign of the Ottoman Empire andTurkish was widely spoken in Tripoli in the late 19th, it was needed to get a decent job, is it old turkish ?

jdowning - 12-2-2007 at 01:52 PM

The bowl profile is a lot closer to the Arnault lute than I thought. From the depth of 20 cm that you gave earlier ALAMI, I assumed that it was a deeper profile whereas now it seems to be very close to a semicircular section which would make the depth around 18cm and conform to the Arnault geometry (as well as lutes as late as the early 16th C)
Due to the close correlation of data I would like to imagine that the Al Arja family of oud makers was indeed working to very early traditions of oud geometry handed down through generations of luthiers.

Peyman - 12-2-2007 at 02:08 PM

Alami, have you tried using a lamp, as Jameel has on his website? http://www.khalafoud.com/bracelocations.htm

jdowning - 12-3-2007 at 06:18 AM

I tried the tuning fork method for locating braces given by Jameel but was unable to get any positive results after trying on a number of instruments. Is there a technique involved as the vibrations of a tuning fork attenuate or fade very quickly?

I like the idea of a strong light used to illuminate the interior of a bowl so that the bars can be seen through the thin soundboard. For instruments with rosettes where it is not possible to physically insert a light source into the bowl, Jameel suggests using a 'strobe' light directed through the sound hole so that there is sufficient reflected light to illuminate the bars which can then be photographed in a darkened room with a long shutter exposure time. Is a 'strobe' light just a regular high intensity electronic flash unit from a camera or is it a stroboscope light that emits regular light flashes for a period of time - which might give the camera a better chance of recording a clear image?

Jameel has also already tried the electronic stud detector which he reports does work but is only sensitive enough to give an approximate bar position. I wonder if all stud detectors are more or less alike in this respect or if there is a super accurate brand on the market that might do a better job?

jdowning - 12-4-2007 at 11:54 AM

Another proportional dimension that seems to fit ALAMI's Al Arja oud is that given by Al-Kindi in the 9th C which is that the point where the strings are struck (ie the centre of the 'plectrum guard') is located at 1/10 of the overall string length.

ALAMI - 12-4-2007 at 04:18 PM

OK you'll make fun of it, I am expecting the worst and am psychologically prepared but

....... .... IT IS WORKING :xtreme:

Definitely worth adding to "the non intrusive non destructive brace investigating method where curiosity doesn't kill the cat"

Peyman - 12-4-2007 at 04:52 PM

Alami,

Are you able to work out what words are written in the rosette, even if you can't decipher their meaning?

David

jdowning - 12-5-2007 at 01:45 PM

With the local hospital definitely less than willing to cooperate in allowing use of their CAT scanner for 'non-medical' purposes, I went out today and bought an electronic "stud finder" from a local hardware store with the intentions of running some trials to test it as a "brace finder", all in the interests of science, research and lutherie. I bought a "Zircon - StudSensor SL" for $20 (including battery) as I was impressed with the flashing, multi colour, scan mode, LED's, the auto calibration LED and the laser like SpotLite Pointing System (not sure what the 'SL' means but, anyway, it seemed impressive at the time - as did the plastic packaging).
The device was tested on an old lute soundboard - so that I could readily verify the accuracy of the results. Unfortunately, it did not work as expected - well actually not at all - with LED's flashing wildly and the SpotLite then 'marking the spot', like a "Retriever" hunting dog 'pointing' to a game bird - the best that I could achieve was to locate the gap midway between two braces!!
So, what am I doing wrong here? First the tuning fork method failed and now this.
Ah well, I can always use it for house repairs I suppose.

ALAMI - 12-5-2007 at 04:41 PM

Like Samir said: anything goes in this beautiful country (the worst and the best.... part of its charm)

The funny thing is that the doctor is not someone I know, I just called the medical Imagery center facing my work and asked to talk with the radiologist, I told him that I have a 115 year old patient who needs a scan, he was impressed and asked if I need an ambulance so I told him that I will carry him myself as he is not very heavy, he started to get angry so I told him the truth:
It's not a human, it is one of the oldest oud alive in Lebanon if not the oldest, he laughed, which means yes.

He worked for about 2 hours, I have the full data: the dimensions of the braces from all sides, the thickness of the wood grain and the profile of the braces and a full 3D reconstruction of the 2 small fan braces.
Finally when it came to money, he refused to get paid but he said that it is the first time that he really would like to hear the sound of the patient, I played a taksim for him, that was the cost.

So Doc if you tell your non-oud-doctor that oud is a part of your heart (you can use a Roumy poem) you may convince him and it would be covered by insurance (an extra taksim could be required)

Hey Mat, I think that now the aliens know where they should land the next time (and hearing our politicians these day I think they already did)

David, regarding the rosette, I will try to do phonetic trascription but there are many possibilities when you don't know the meaning as interleaved calligraphy may have more than one possibility of reading.

jdowning - 12-5-2007 at 05:52 PM

Nice work ALAMI - this must be an important 'ground breaking' study in the use of current x-ray technology (CAT scan) to further research into early instruments. Thanks also to the anonymous empathetic and enlightened radiologist who made the experiment a reality. You should consider formally recording and making available your experiences and findings in this project for the benefit of future researchers? Bravo!

Dr. Oud - 12-6-2007 at 08:50 AM

The wall stud finder uses a reading of the dielectric constant of the material it is held against. There is a significant difference between a wall stud and sheet rock or wall board, so the reading is fairly accurate for that application. Since the soundboard and braces are both wood, the dielectric constant is the same, so the reading will vary only in signal strength, and these devices are not sensative enough or calibrated for the minute difference in signal due to the mass of the material. That's my theory based on the principle used for stud finders. There might be other possible methods to find braces - ultrasound imaging. May be cheaper than a cat scan or MRI; or particle dispersion - sprinkle sand or other small particle media over the face, excite the soundboard with a vibrator and the particles should collect around the braces and disperse between them.

jdowning - 12-6-2007 at 09:34 AM

Thanks for the explanation Richard. I also tried a test with a 3/8" thick piece of pine laid over a length of 2" square cedar - figuring that there might be a scale effect - but the readings were totally random and inaccurate which confirms what you say. Pity.
I am going to try your suggestion of vibrating the sound board but am not sure that I would want to use sand but I suppose that there might be a critical particle size so will experiment a bit.

zalzal - 12-7-2007 at 10:00 AM

There is a radiographie of an oud in Wissam Joubran site

http://www.wissamjoubran.com/fr/Photos

ALAMI - 12-7-2007 at 12:48 PM

The Al Arja Bracing is interesting:

The bracing is very thin but it survived 115 years in bad conditions, in a humid city and when I found it wasn't even in a case or even a linen bag (like old ouds)

_8 full length braces (there is one under the last line of text
_2 fan braces on the bridge level
_No horizontal braces around the hole

I don't have enough experience to draw any conclusions I will let this to the experts. Even though the shape is identical to De Zwolle manuscript the barring is different.

Regarding the scan experience I can tell only what I learned from the radiologist and it should not be considered as a scientific reference
The scan in fact can have many resolutions (measured in mm in terms of increment, or slices), the radiologist did a full scan for the Fan braces region and for the brace that is just in front of the bridge in the direction of the hole. When I say a full scan it is the scan that outputs full 3D data, in this sense the full bowl scan is not a full scan it is a general view that is not highly accurate on the edges resulting in a distortion that is easily fixed, the general view is limited to 50 cm in scaner He used, may be it is enough for lutherie use, I don't know.
Ideally the instrument can be scanned in small slices and a full 3D model can obtained and delivered on CD with its viewing and measuring software. This scan can take between half an hour or 2 hours depending on resolution and scan speed. But the study and the measurments can be done later on by the researcher on any PC using the free software that is on the CD.

Voila

An oud made in Tripoli - Lebanon in 1892 is "according" to De Zwolle manuscript 1450, pure coincidence ? or shared ancient ways ?


This is extremely interesting since some consider Zwolle's description to be ¨theoretical¨ and not authentic for the lutes of the period.

A 'standard' lute barring for the early 17th C is given by Marin Mersenne in his "Harmonie Universelle", Paris, 1636. (I gave a translation of the relevant passage some time ago on this forum so it is not necessary to repeat it again here).
To summarise, Mersenne gives the bar placement on the belly of a lute by dividing the belly into 8 equal parts from the bottom of the belly (point 0) to the lower edge of the neck block (point 8). The rose centre is positioned at point 5. Bars are positioned at points
2, 3, 4, 5, 6 and 7 (ie the bar at point 5 runs across the centre of the rose). The distance between point 0 and point 2 is divided into 3 equal parts and the bridge is located on part 2. Mersenne then states that some makers add additional bars - if the belly is not well supported in places - as well as smaller bars below the bridge.
The attached image of an early 16th C Italian lute belly (Magno Tieffenbrucker, 1609) illustrates Mersenne's barring arrangement quite well. The belly also has evidence of scribed marks made with dividers used by the maker to lay out the belly geometry. In this case the layout differs only in that additional bars are placed on each side of the bar on point 5, and there are two bars equally spaced on either side of point 7 in place of a single bar.
Lutes of this period did not have a large end block at the lowest part of the bowl (as is current oud practice) but instead had a thin end plate to provide additional reinforcement and stiffness of the bowl at this location. Additional stiffness in the area below the bridge - in the absence of an endblock - was provided by additional bracing (a bass bar and diagonal treble bar) - typically as shown in the image.
The barring of ALAMI's Al Arja oud matches the Mersenne barring closely if the inside edge of the bottom block is taken as point 0 (and not the bottom of the bowl) - except for the below bridge bar (which is located in the same position as the bass bar as well as the diagonal treble bar on the lute), as well as the additional bar placed close to the neck block.

Just for information. To continue with more about barring, the Egyptian(circa 1920 but might be earlier?) oud that I am currently restoring on this forum is unusual in several aspects of its construction which seem to be more lute than oud like. For example, it does not have a bottom block but instead has a thin end plate (about 2mm thick tapering to a thin edge all around) as would be found on a lute except that the end plate does not extend to the edge of the bowl and so does not provide direct stiffening of the belly in this location. Instead, the banding around the edge of the belly (which provides a controlled weakness around the edge of the soundboard) does not extend to the bottom edge of the bowl but stops for a distance of about 250 mm below the bridge position. This unusual feature I now believe is an indication that the belly is original and not a later replacement.
To summarise, it would seem that additional stiffening of the area of the soundboard below the bridge (ie between bridge and bottom of the belly) is an important feature of both early oud and lute design. This additional stiffening may be provided by a thick bottom block (as in the Arnault lute), thin end plates, an additional bar below the bridge (a feature of ouds but not surviving lutes), 'fan' bracing below the bridge or a combination of these.

jdowning - 12-20-2007 at 06:38 AM

I should add that the Egyptian oud in the previous posting has another unusual (?) feature in that the lower part of the soundboard that does not have any edge banding (binding) already noted was covered by a narrow strip of thin, green coloured leathercloth (also known as faux leather or leatherette) glued in place. The purpose of this was originally probably twofold - to further reinforce that part of the sound board and to protect the edge from damage.

It occurred to me that this is another 'lute like' feature. Lutes of the 17th C/18th C that did not have protective edge banding often had the soundboard edges protected with a 'lace' - that is a narrow strip of thin parchment glued in place covering the soundboard/bowl joint.

So far, I have not been able to find when leathercloth was first manufactured but it has certainly been used for binding books since the mid19th C (and, of course, in its more modern form with synthetic plastic coatings is widely used today). This, however, does not help much in dating the oud as early types of leather cloth were used well into the 20th C prior to the invention of plastic coatings.

Ronny Andersson - 12-20-2007 at 02:49 PM

For what is worth I have seen the Tunisian Kuitra with an edge covered with leather. There is one in a Swedish museum from I believe early 19th century with this detail. Sometimes you find also leather/cloth glued on the lower part of the soundboard in a very decorative pattern.

The geometrical construction of a 15th C lute given by Arnault de Zwolle does not quite match the profile and sound hole position of the Al Arja oud.

In an article "Lute Design and the Art of Proportion" by Gerhard C. Sohne, the author proposes a geometrical construction, of elegant simplicity, for an early 16th C lute - based upon the familiar 'Pythagorean' right triangle having a hypotenuse measuring 5 units and the other two sides measuring 3 and 4 units respectively. The construction is given in Fig.1

No lutes of this design survive so Sohne selected an example from the iconography as evidence that the proposed geometry was an historical possibility. The carving of Pythagoras playing a lute by Jorg Syrlin the Elder (c. 1470) is in Ulm cathedral, Germany. While the profile of the lute, sound hole diameter and position match the geometry closely, the length of the fretboard is too short as it is only of sufficient length for 7 frets - not 8. However 7 frets to the neck joint would have been typical for a lute of the 15th C (as it also would have been for an oud of the Medieval period).

Although no lutes of this design survive there are some old ouds that do seem to conform to the geometry. One is the Al Arja oud - except that the Al Arja oud has the traditional length of fingerboard that is 1/3 string length.
Working with a high resolution "full face" image of the oud - taken with a long focus lens to minimise any optical distortion (kindly provided for this exercise by ALAMI) - the geometry was modified slightly (Fig. 2) to obtain the very close match evident in the attached overlay image. Note that the neck length is a few mm short of 1/3 string length due to loss of material caused by repeated repairs and adjustments to the neck over time. Also note that the actual sound hole diameter is the diameter of the open area of the rosette pattern. The centre of the soundhole is a distance of 1/3 string length from the neck joint - i.e. according to oud traditional design.

This result suggests a possible connection with early oud design in the Middle East and lute design of 15th C Northern Europe.

The research an information shared by everyone is astounding. I am very impressed and thankful that so many have spent so much of their time to help solve this mystery. I now feel like I have sufficient information to restore this oud to something close to it's original design. I have been reducing my work load this year in order to restore more of my collection of broken old ouds, and this one will definitely get on the bench soon. Thanks to everyone, with special appreciation to Alami and jdowning for their valuable input.

Good luck with the restoration project Richard. I look forward to seeing how it turns out.

I was in a bit of a rush to post the details of the Ulm lute/Al Arja oud geometry so will add the following comments for further clarification - although it should be self evident from the geometrical layouts.
Location of the neck joint at 1/3 string length is the Pythagorean ratio of 3/2.
The Al Arja geometry starts with the sound board profile determined with the Pythagorean 3:4:5 right triangle as its basis. The width of the the sound board is 4 units. the bridge is 1 unit from the bottom of the sound board The neck joint position is then determined knowing the width of the fingerboard at the neck joint (about 55 mm for a six course oud).

The top of the sound hole is located at B - 4 units from the bottom of the sound board. The distance from neck joint to bridge is then halved to give the location of the centre of the sound hole. This gives a sound hole centre that is bit lower than that given by Sohne's geometry and so results in the larger sound hole diameter matching that of the Al Arja geometry.

The most popular prevailing theory is that the European lute came from the oud of Moorish 'Spain'. However, the other possibility is that it may have been introduced to northern Europe directly from the 'Middle East' (Persia via Turkey perhaps?) as a result of the historical connection of the so called 'Holy Roman Empire' (= Germany) with the Roman Byzantine empire to the East. (beware - not sure of my historical knowledge here!). There is also a connection with Charlemagne and the founding of the town of Zwolle in Holland (Arnault de Zwolle). Interesting that a majority of surviving European lutes were made by luthiers of German descent. All speculation at this point in time, however!


ALAMI - 6-20-2010 at 10:15 AM

When I got this oud, I was just happy that I found a 19th century oud (1892).
Of course I wasn't aware of its uniqueness, it was John who spotted the unusual geometry and he was since intrigued.
His latest finding is most interesting, this Pythagorian triangle geometry is simply elegant, the oud is so easy to hold and it sounds divinely good old Arabic 

Still we know nothing about the Arja brothers except they had a shop in Tripoli Lebanon near the old Ottoman Serail ( that exists no more), it was a "quartier chic" location for the late 19th century, so we can imagine that they were rather wealthy.
I was able to discover lately that the unreadable rosette is in fact maqam names in Arabic letters written in a very intricate way.
The most important detail is that the two small ornaments on the pick guard are Orthodox crosses.
 
The theory of the oud went to Europe through Andalousia has always been considered as an evidence, a romantic one. It is shortsighted to consider History like a one way road. Many forget that the foundation of modern science in Europe was brought by the scientists who fled from Constantinople after it fell in 1453 ( I think). Lutherie could be among these sciences.

On the other hand,Greece, the Balkans and most of Central Europe were, and still, mostly orthodox so we should also consider the Church and its Byzantine music and instruments as a possible vector of transmittance. It would explain John's question about the fact that most early lute makers were on the German and not the Latin side of Europe. 

The Christians in Tripoli Lebanon were mostly orthodox, what if this kind of oud design was a common traditional one that the Arja Family kept making up to the late 19th century, we haven't found enough old ouds to confirm ,or not, this theory.

So much history in such a simple instrument.
Thank you John and, Richard, we're looking forward to see those restorations, it's been a long time, we miss those projects.

To add a few more thoughts about the possibility that the style of lute of Renaissance times (i.e. c.1450 to 1600) may have come to Europe not from the Moors in the Iberian Peninsula but directly from the middle East via Germany.

Tinctoris (Naples 1497) wrote that " While some play every sort of composition most delightfully on the lute, in Italy and Spain the viola without a bow is more often used". It should be noted that at this time Naples was a dominion of Spain under direct Spanish rule.
It is curious why the Spanish courts at the time had a preference for the Vihuela da Mano and its almost identical counterpart, the Viola da Mano, over the Lute (all three instruments may be considered to be interchangeable). Indeed, 1536 saw the publication of the works of Francesco da Milano (the greatest Italian lutenist of his time) for viola da mano entitled "Intavolatura de viola o vero lauto ....." (Tablature for viola (da mano) or true lute ...). The two books were published in Naples.
The attached image of the legendary Orpheus playing a Vihuela da mano (tablature for vihuela "El Maestro" 1536, by Luis Milan) also might support the notion that the Spanish considered the vihuela to be superior to the lute.
It has been suggested that this preference may have come about because of prejudice and the activities of the Inquisition against the Moors and their culture (and hence any instrument that might resemble an oud). However, this does not appear to be the case as there is ample evidence in the iconography, court inventories of Spanish royalty, literary works etc. to support the proposal that the vihuela coexisted with the lute in Spain (as it did with the viola in Italy). This is also perhaps an indication that the Spanish did not consider a lute of the time to be the same instrument as an oud.
According to Pepe Rey in a recent article "Dos retoques criticos al libro 'A history of the Lute', Hispanica Lyra, Journal of the Spanish Vihuela Society, the Spanish dictionaries of the time suggest a Greek origin for the lute and that "some even think of it as coming from the Rhine Valley" (Germany again!).

Note also that some of the finest strings for lute available in the 16th C came from Germany (from the cities of Monnekin, Mildorpe, Nurenburge and Strassburge - according to Dowland, "Varietie of Lute Lessons", 1610).

Two attached images from lute books containing the works of Francesco da Milano both published in Northern Italy in 1536 depict the lutenist. Note the profiles of the lute. The engraving from the book published in Milan is rather quaint in its execution but the intent of the artist seems to be unmistakable in representing the lute having an 'almond' shape with semicircular bottom section and 7 frets to the neck joint. The engraving in the Venice publication is more precise and, although represented in perspective view, the lute profile would appear to closely match that of the Ulm and Al Arja geometries. Note also the narrow oud like neck - but with 8 frets to the neck joint.

One final observation, the bracing of the Al Arja oud includes two small lute like 'fan' braces below the bridge - not a traditional feature of modern ouds and, therefore, considered by some to be of Western European origin. Or could it be that this was a feature of early oud barring (now long forgotten) that found its way from the middle East to European lute design of the 16th C.?

The length of the neck of the oud originally posted by Richard is 297 mm but 7- 11/16 inch converts to 195.28 mm which is about 1/4 total length of the instrument so this latter dimension is to be taken as the correct dimension in calculating the original string length and geometry of the oud that appears at first glance to be a modified version of the 14th C Persian described in 'Kanz al-Tuhaf'.

So the dimensions to be followed are neck length = 195 mm, body length = 568 mm, body width = 323 mm, body depth = 203 mm.
Scaling from Ronny Anderson's image of the fingerboard gives a neck joint width of 5.7 mm - about right for a 6 course oud.

jdowning - 7-22-2011 at 12:16 PM

The fret locations on the fingerboard are clear enough from the close up image provided by Ronny and, as it appears to be relatively free of optical distortion, it should be OK to scale dimensions.

The attached image compares fret positions as measured with 12 Tone Equal Temperament and Pythagorean.
Equal temperament spacing is historically appropriate for lute fretting as is Pythagorean spacing for 14th C oud (but does not include intermediate 'quarter tone' frets).

It can be seen that the finger board is long enough to accommodate 7 frets spaced according to these systems. The 7th fret position is at 195 mm from the nut so the string length - deduced from the fret positions - is 3X that dimension or
585 mm (which agrees with Richard's estimate of 586 mm).
It should be noted that in practice the frets may deviate slightly from the calculated positions dependent upon the fret gut diameter, string diameter and string tension. The displacement of the measured fret positions towards the bridge is consistent with practical fretting based upon 12 TET - i.e lute fretting. So, whoever tied the frets on the neck intended to play the instrument polyphonically like a lute - not like an oud.
Oddly - as Richard notes - this string length seems to be out of proportion to the overall dimensions of the oud. Indeed the bridge would have to be placed somewhere near the widest part of the sound board to conform to this string length. This implies that the oud was not originally made to be fretted but had been altered at some time by repositioning the bridge to shorten string length so that seven frets could be accommodated on the neck - perhaps by a European 'early music' researcher in the late 19th/ early 20th C looking for an instrument on which to explore the surviving lute repertoire?

So, if the existing fret positions cannot be used to deduce the original string length of the oud where do we go from here?

The perfect proportions of an oud - as given by the mediaeval period writers Ikhwan al- Safa (10th C) and Kanz al-Tuhaf
(14th C) are that the neck (ie fingerboard) length is 1/4 of the total length of a oud. This is of sufficient length to accommodate the range of fret positions dictated by these early theoreticians ie up to the last fret - the 'fourth finger fret' - equivalent to the fifth fret position on the 12 Tone Equal Temperament scale. The early German lutes of the late 15th/ early 16th C also originally only had five frets on the neck.

The Al-Tounjy oud is of this proportion except that the neck has been made slightly longer in order to create a sufficient neck joint/ finger board width to accomodate 6 double courses (the earliest ouds only had four or five courses).
Although the Al-Tounjy oud - made in 1889 - did not originally have frets, the fourth finger position would have been located close to the neck joint - its exact position being dependent upon string length.

Ronny Anderson's 'full face' image of the oud suffers from some optical distortion so it is not possible to scale exactly from the image. However, taken together with Richard's measurements it is possible to make a reasonable guess at what the original geometry may have been although this can only be accurate to within say 2 to 5 mm due to the damaged condition of the oud and possible distortion of the bowl.

The attached image is the proposed geometry drawn to scale and is largely self explanatory. The upper sound board profile is the same as that given by Kanz al-Tuhaf. The bridge position is 4 finger units (of about 20 mm) from the bottom of the bowl - the proportion given by the 14th C Ibn al-Tahhan oud. This gives a string length of about 680 mm (shown as 675 mm which appens to be a significant string length for both the early ouds as well as some of the late 17th C lutes - the relatively long string length providing optimum performance for gut bass strings).
The sound hole diameter and placement is a guess based upon the 16th C Maler and Frei lutes that had this long elongated profile.
For comparison see "Old Oud Compared to Old Lute Geometry" on this forum.
Given the similarity of geometries the original bracing of the surviving Maler sound board might be an indication of the bracing used on the Al-Tounjy oud.

A convenient tool for calculating fret positions for a number of historical systems can be downloaded from the 'Lute Society of America' website. The software does not work on older version of Microsoft Works but does so on the free open source 'OpenOffice' software.

Found this "oud" at the museum of Jewish Heritage, in NYC. (No, I'm not Jewish)

The museum calls the oud "Turkish" and says it dates from late 1800's. I find this odd for a couple of reasons.

I know its hard to tell from the photo, but the bowl seems to be of a European lute, and is very shallow, not half round.
The rosettes are carved from the same piece that the top was made of. (like lutes) No holes were cut out and there are no additional materials which the rose was made from, then glued on. This is not the case.
You will also notice frets just past the neck joint. Which have been planed down so that the surface of the soundboard there is flat.
I don't believe the bridge, pickguard, neck, or pegbox to be original.
Also hard to tell from this photo, small pearl star of David inlays on the fingerboard.

My thesis on this odd instrument is it might have been a lute, which was later modified to be played as an oud in Turkey. Whatever the case is, it have had to come to the U.S. by Jewish immigrants.



jdowning - 7-31-2011 at 05:00 AM

Hard to say from the image due to low resolution and foreshortening. It might originally have been one of those German lute/ guitars made in the second half of the 19th C. - later converted to an 'oud'. Note the massive guitar like bridge, frets on the sound board and inlay dots on the fingerboard and sound board edge banding/purfling.
Or perhaps it was originally a Turkish 'lavta'?
The profile of the sound board could be either lute or oud but a shallow bowl is not characteristic of either instrument.

The peg closest to the nut on the bass side does not appear to be fitted to the side of the pegbox?! Also the peg box seems to be crescent shaped? - but impossible to tell from the image.

bulerias1981 - 7-31-2011 at 08:23 AM

the angle is a little funny, but the peg on the left is fitted into the pegbox as normal, and pegbox is the same angle and shape of standard oud pegboxes.

jdowning - 7-31-2011 at 02:20 PM

So a Turkish 'Lavta' with shortened neck may be the answer?
