If you bend the touchpiece part of the key, below the pivot, I suppose it
need not affect the angle of the pad. I had ruled this out just because
of the (possibly quite subtle) change in thumb technique which might well
be needed. There would still be a problem if this part of the key were to
be bent asymetrically.
When I was just starting, I found the register key touchpiece to be
disconcertingly far away from the edge of my thumb, which tended to lift
off the ring - this improved with practice (and better instruments!). It
might actually be easier for a beginner if the
cork on the key was *very* slightly buit up to reduce the key opening,
rather than bending the key.
