The two keys on the chalumeau are exactly opposite one another and are the
same size. The clearance of the key above the hole is about the same. Used
singly either one will produce an A, although normaly the upper one is used.
Pressing BOTH keys gives either a B flat or a B natural, depending on the
exact set up of the instrument. This turns out to be useful since one can
adjust the instrument for a particular piece depending on whether B flat or
natural is needed (and there are examples of both in the repertoire). I have
not yet discovered a way to set up the instrument to play both, though it
might be possible to set it up to play B natural and lower it with the
thumb- tricky to get it exactly right. (The thumb height makes a huge
difference to the pitch- you produce an A flat by pressing either key and
closing the thumb hole for example.)
There are a few makers of chalumeau these days, mine are by Brian Ackerman
in the UK.
