 The Clarinet BBoard

I've researched this and still don't have a very secure answer to this. (I'm always asking myself "why".) But how is there a difference between polycylindrical and conical? They both expand in a similar manner, and I can't even tell the difference when I look down a poly bore and a conical bore. Even if it's different at a microscopic level, I fail to see WHY that would matter... as they are both expanding as they go further down, so the air should even in a circular motion follow a similar "slipstream"
Am I missing something important here, or am I just utterly clueless?? I've taken absolutely no physics whatsoever so I can't even try to compare scientifically.
May there's a diagram out there of a poly bore vs. conical bore. Can anybody direct me to one, or try to explain it in small words I'll be sure to understand? I AM still in high school, after all.

Hi David,
Go to www.sfoxclarinets.com
You'll find a fairly short, layman-friendly article on clarinet acoustics which touches on polyc./comical clarinet bores.
That typo is too good to delete!

I would guess that a comical bore is someone who consistently, and persistently, tells old, stale jokes. (Either that or the inside of a saxophone.)

Back to the bore question, David, we had a bore type-configuration discussion just last week [search the Phorum}. I agree that the diff. between "truly-conical" and polycyl., with such [usually]minimal enlargement of the top of the UJ, is scarcely detectable in playing diffs. [to me], also hard even to measure, I leave it to the [opinions of] the real pros. There prob. is some improvement in the pitch accuracy of the twelths [clarion register to me] but again hard to "pinpoint". I just assume the makers know what they are doing, and reserve the right to make my choice of horns. Don
