<html> Hello, Robert You don't say what kind of piano. Two things you can try: (1) move your head around. Sometimes a beat can be heard clearly in one place, but another place nearby it is almost indistinguishable. (2) In case you're tuning a console -- check to be sure that the dampers are completely clearing the strings in the tenor. Sometimes split wedge felt goes too far past the strings, and drags on the middle string even when the key is all the way down. Otherwise -- practice, practice.

The problem is that the beats are so weak they are hardly perceptible. I have strip muted the piano and was able to tune A49 on the piano to the A440 tuning fork by comparing the beat rate of the note and the fork with F21. I am now trying to tune the other notes within the temperament octave and get the beat rates of the F-A, A-C#, C#-F and F-A to gradually increase from 7 bps to 14 bps, but they are very difficult to hear. What can be done to hear the beats more clearly? I have been studying tuning for several months now, but the beats of the intervals are still difficult to hear. I don't have much trouble with unisons as I can hear the beats more distinctly, and the improvement in the quality of the note when I reach the pure state is very noticeable.   I have an SAT III tuning device that enables me to tune the piano very well, and to check my aural tuning, but I want to be able to tune the piano completely by ear so that I can eventually pass the PTG examinations. Thank you for your help.   Robert Finley</blockquote></html>
