<html> Are you hanging the fork from a couple of fingers and using the bottom of the keybed for sounding? That's what the bump or ball or whatever is best for, on the main post of the fork. I actually carried a C523 tone bar for years, to avoid those problems. Also, a regular rubber wedge mute can come in helpful on naturals, as you can play the note and slip the mute under the fall or upstop rail pretty quickly. The mute is also a good way to sound an organ note long term when matching instruments in a church, or whatever. It can even be used for "ghosting" on one OR two pianos. A simple clothespin can disable a damper, if you need to.... As was mentioned, you can also change your temperament sequence.

I mute one of the two strings of F21, sound the tuning fork and listen to the beat rate. I then would like to be able to play F21 and A49 and adjust the centre string (side strings muted) to provide the same beat rate. The problem is that I can't play both these notes and adjust the tuning pin to hear when the beat rate becomes correct. The distance between these two notes is too far and requires two hands to play them, so I can't adjust the pin as well.   My piano is a Yamaha G3 5' 3" grand, and it was bought in the UK. It only has two pedals and doesn't have a sostenuto action, so I can't use that to keep F21 sounding while I play A49 with one hand and manipulate the tuning hammer with the other. The only solutions I can think of are to somehow disable the damper of F21 or to put something heavy on the key after it has been played to hold it down.   Until now, I adjust A49 until the pitch sounds the same as the fork and then check the beat rate with F21. It is a trial and error method, and isn't very satisfactory. It would be better to hear the change in beat rate until it becomes exactly right.   Do you have any suggestions what the best solution might be? Thank you very much.   Robert Finley  </blockquote></html>
