I've often wondered about this. I have always theorized, with no
scientific evidence to cite at all, that the reason an A Clarinet is
normally made with a smaller bore was to avoid having to lengthen the
instrument body (and therefore the tone hole/finger spacings) any more than
necessary. The reason for this would presumably be a less drastic change
for the player's fingers when switching instruments. If an A clarinet were
made longer with a correspondingly larger bore diameter so that the pitch
of the instrument were still correct, would the resulting instrument play
more freely than most modern A clarinets do? Or would the additional
resistance over what we get from a normal Bb clarinet still be there, now
because of greater air volume that needs to be moved?
I guess the ultimate direction of this question is to ask whether for the
price of a little more hand stretch (or maybe some additional mechanical
linkages to reach where my fingers wouldn't) I could in theory end up with
an A clarinet that doesn't fight back as hard as most do? Have there been
experiments in this direction?
