Well, my point is that "low-bass-clarinet" doesn't necessarily cut it, because
you have multiple different extended members of the clarinet family, and even
within the same manufacturer, their fingering systems vary.
For example: going by the images and information on the Buffet Crampon website,
their basset horn comes with an alternate left hand Ab/Eb key; their basset
clarinet doesn't. I also suspect that their basset clarinet has only one thumb
key (for low C) while their basset horn and low-C bass may have more.
So, if we're REALLY going to ensure that diagrams are accurate, then we probably
need to do a careful survey of the fingering mechanisms for basset clarinets,
basset horns, and low-C bass, contra-alto and contrabass clarinets, for each of
the main manufacturers (Buffet, Selmer, Leblanc, Yamaha).
I think it's probably sane to limit ourselves to current models -- to try and
address the past would be to open a huge can of worms -- but even with this
limit, there's a fair number of different diagrams to potentially cope with.
In any case, at a minimum you need 3 different diagrams:
-- regular clarinet (to low E)
-- full Boehm (to low Eb)
-- extended (to low C)
... and that's before you even think of trying to support Oehler-system
instruments.
There may be more, but I think that's it. If you like, I could see about
making a scan of a page or two from Philip Rehfeldt's "New Directions for
Clarinet" which indicates appropriate key names and has examples using a
key-name based fingering system.
Mmmhh, sounds interesting.
I'll get that scan this weekend.
