I think the resistance is more to do with the mouthpiece facing and reed strength - Viennese players use a much closer tip opening and harder reeds than German players.

But, other things equal, a smaller bore should have more resistance than a larger bore, shouldn't it? Isn't that why some manufacturer's A clarinets have more resistance than a Bb of the same model?
Best regards,

There is also the issue of tone hole size/design. Technically Jack Kissinger is correct, but in reality it's seldom that simple. dn

I also agree that this is NOT a simple correlation at all. As a matter of fact the bore dimensions on the Wurlitzer clarinets alone have been altered quite a bit over the years with 'other' factors being at the root of this change such as 'focus,' 'power,' 'intonation,' to name a few.
I am currently fretting over this slight difference myself getting closer and closer to ordering Gerold (Viennese) clarinets advertised at a bore of 15 mm which does seem large to me. As I inspected the Selmer website just to have SOME comparison, the Privilege (which I've played) appears to have one of the larger bores amongst this family and yet I find that this model plays with the MOST focus and power of the Selmers I have tried to date.
Gerold contends that his clarinets are of the "darker" sound which he also partly achieves with thicker walls to the instrument body.
So, this was a long way of agreeing with Chris P in that I don't think resistance is the main factor here.
Good Luck !!!!

I think there could be some resistance between barrels. For example some of the Moenig barrels can be stuffy due to the reverse taper, compared to the barrrel that you get from Buffet. Also the Moenig barrels can have a smaller bore. I've measured a lot of them.
If it's the same barrel company I'm not sure, but if there is a difference it's probably slight.

Just checked the specs of the Privilege and it's got a 14.6mm bore which is tiny in comparison to older Selmers (RI, BT, 55, CT, Series 9) and still narrower than the Series 10 and 10G. Also narrower than Buffet R13 (14.65mm) and RC (14.75mm) bores.

Thanks Chris, though I was referencing their more current stock (14.35 for the Recital and 14.50 for the Signature).
I never played on anything before the 10G.
Of course all this is comparing apples to watermelons.

I'm not sure, and it could be different, but I know that larger bore didgeridoos are often harder for me to play than smaller bore ones (approx same length). Not that this necessarily applies to clarinets.

Air flow down the bore is negligible. It's the vibration of the air in the bore that produces the tone. As Kincaid said, you don't have to fill up the instrument with air. It's already full. You "ring it like a bell." Even the smallest bore is too large to provide noticeable resistance to the amount of air human lungs can exhale.
The mouthpiece lay and baffle, plus the taper of the reed, determine the amount of resistance a player feels. The shape of the bore can produce a feeling of resistance because the modes of vibration can be in or out of synch with the vibration of the reed, but even that is small compared with that of the mouthpiece and reed.

You're all forgetting TONE HOLES. having spoken more than once on related topic with people who actually MAKE instruments, they have always instisted on the importance of these re intonation (obviously) but also resistance, resonance and tone quality.
