Also= you go back and clean up unisons that you already tuned that= might have changed. Of course making the correction to the= right string... We are still waiting for an explanation of "shimming" unisons. = This morning I finally tuned my own piano and decided to lay in a= temperment aurally, which I haven't done in a long time. I= didnt do so well. When I checked it with my SAT III. I was= about 1+ cents sharp on most of the notes even though my 4ths &= 5ths sounded great. I didn't have A3 in the right relationship= to A4 or sharp of what it should have been. Everything else in= relation to the A3 was sharp. When I went back and adjusted to= the SAT III the temperment cleaned up wonderfully. Even= progression of fast beating intervals, clean 5ths & and slow= beating 4ths.

Check C4F4 fourth,= using Ab3 as reference note. Between F3 and F4 tune A3 and C#4, making 4:5 beat ratios. >From C#4 tune F#3, using A3 as reference note. >From F#3 tune Bb3. Check F3Bb3 fourth, using C#3 as reference= note. Check Bb3F4 fifth, also using C#3 as ref note. >From Bb3 tune D4. Check A3D4 fourth and F3D4 sixth. and so on predictably, tuning the rest of the temperament in this= sequence: G3, B3, Eb4, Ab3, E4. The red notes do not have to be "right" to function as= reference notes - they just need to be a single frequency that= produces a usable beat. If they are an open unison that is not= perfectly in tune with itself, they do not work as reference= notes. In practice, I mostly use Tunelab, so in practice I don't do as= much checking as I think I should, but I am trying to unravel= this single-mute thing and understand what it is that you= actually do. So please show me your bearing plan, with checks,= and open my eyes.

How do you= do this efficiently using a single rubber mute? Do you mean you use strings you haven=92t tuned yet as references?= I don=92t do that; I just tune as I go, using the tests I=92ve= learned within the notes I=92ve tuned. Email me privately, Jason,= and we=92ll talk about this so you can get an idea of what I=92m= doing....
