All of this acrimony! And all this (be)moaning ...
A good tuner is not a $5 box with yes/no lights. It shows WHERE a played note lies, not just whether it is or is not an ET "D".
Pitch falls along a frequency continuum, but display in Hz is not too informative. So a tuner can be set up for the center notes of an ET scale, or
pythagorean, or a specific maqam, or whatever reference grid you want to set up, and then it shows deviation of what you sing or play from those
reference notes down to tenths of a cent.
It's up to the player to at least know where the notes of a given maqam or scale are supposed to be. The tuner only shows where your notes are
landing, how repeatably you can play them. I'd say that's helpful, |
