How do you define the perfect and/or the acceptable unison.    FWIW, I have absolutely no trouble with the bass or the high treble, it's that dang tenor section. It seems like the better I get, the more I can hear, the worse I actually tune.    Comments anyone? Benny L. Tucker </BLOCKQUOTE> Benny You are trying to get more out of the piano than is "normal." If you can get your unison to sound in tune for 2 or 3 seconds, call it quits. There are too many variables in the piano for the three strings to stay perfect for any longer than that, especially in the tenor part. By the 3rd or 4th second, you're not hearing the actual strings any more. The overtones have taken over, and that is what you are hearing. As a way to get there a little faster, and perhaps you're doing this already, is to tune only two strings at a time. Mute the left string, and match the right string to the middle. Then mute the right string and tune the left to the middle. When A = B and C = B, then A = B = C. Wim </HTML>
