Alvin,

I don't follow your reasoning at all. The maker could just as well
control the pitches emitted by the various holes on an A clarinet by making
them larger and locating them farther from the mouthpiece.

My question could just as well have been:
"Why do makers choose to place the tone holes so near the mouthpiece on an
A clarinet and the compensate with small diameter holes?"
