Larry, not pressing enough the keys may produce bad sound as you say, so we tend to make more pressure when the flute does not produce a good sound. Other problem migh be not closing well the holes in the key (in a flute opened hole). Using silicone plugs might let you determine if that is the problem.
The problem might be that the key does not fit perfectly over its basement too.
If you have sent it to a luthier that sould have been corrected.
If you have the same problem in different flutes, problably it is your fault. Try using plugs.
When I uses a thumb rest in my right hand, the lower notes began to sound worse. I think that somehow the position of my fingers changed due to it and some of the holes were not well closed sometimes.
Now that I have taken away the thumb rest again it is easier to play the lower notes (but my thumb sometimes moves out of its correct position).
For the left index finger using a suplement for the B key is giving me better results than a thumb rest to separate the finger from the flute.
Grace, you are right, I think that too much force is one of my problems.
When I get nervous or there is a quick part I tend to make too much force. I am correcting it and now I make less pressure, but my problems might have that origin: too much pressure over the keys.
Sometimes I think some of the keys do not close perfectly, but not sure (other times the sound perfectly).
This year I will send my flute to a luthier to have a revision. I have not sent it since I bought it several year ago (not sure may be 4).
Tom, thanks for the suggestion.
I will seek for that plastic, it sounds a good idea too. I will try with cork first as it is easy to have a wine cork at hand.
CA glue is contact cement?
The appropiate glue to fix the gadget to the key is the key point in it.
thank you all
