Subj: [kl] C#/G# for Right Hand
Date: Wed, 3 Apr 2002 07:50:10 -0500

Instruments with the articulated C#/G# mechanism usually have an extra
"sliver" key between the right index and middle finger holes that opens the
key. I've never been able to figure out any use for it, other than to be
able to trill with a right hand finger.

I think the "banana key" discussion is about a different mechanism -- a
vertical touch operated by the knuckle of the right index finger, placed
below and outside of the 4 trill keys. It would need its own posts to
reverse the direction of operation, so that it would open the C#/G# key.
This would be very useful, since it would provide a right hand alternative
for this note and would not require any sliding. As Kelly and others have
said, this key is on most oboes, and an oboe specialist should be able to
adapt it to the clarinet.

The "full" Mazzeo model clarinet had a link between the right little finger
Ab/Eb key and the C#/G# key, giving a right-hand fingering. Any patent has
long expired, so the mechanism can be freely copied. However, it was
complex, and it made the action of the right hand Ab/Eb key too stiff for
comfort. I think the banana key would be the better solution.

I also saw recently an ingenious solution for the left-hand Ab/Eb key. It
used the same mechanism as on flute trill keys, with the new key mounted
concentrically with the left hand F/C key rod. The touch was not above the
E/B and F#/C# keys, but outside and below the F/C key. A flute specialist
should have no trouble making it, and a completely separate key should also
be possible. In fact, it would be easy to do with the "standard" design.
The location seems better to me. It doesn't get in the way of the other
keys, yet it's easy to reach.

Best regards.
