 Barrels suitable for Bb and A...How?
Author: Phurster

I notice that Backun advertise it's Fatboy and Moba barrels as suitable for both Bb and A clarinets.

I have them both and they do seem to work fine.

However my Chadash and Tosca Barrels both have a specific marking, for either Bb or A clarinet.
Presumably the bore at the top of the upper joint is slightly different.

does it matter if their is a mismatch between the bores of barrel and the upper joint?
If it does how has Backun got around it?

It matters whether or not the barrel plays in tune with good tone and response with whatever clarinet you put it on. Backun "[gets] around" the difference by producing a range of bore measurements and letting the customer decide which barrel works best with the instrument he wants to use the barrel with. You try several and choose by what you hear and feel.

I don't know that Moennig or Chadash Buffet barrels are truly consistent in their bore dimensions, either, but they are probably meant to be. An A barrel's bore is nominally different (smaller, I think) from a Bb barrel.

Some A clarinets have a narrower bore compared to their Bb counterparts, so the barrels for each will be different.

The opinions I express are my own.

So it doesn't matter if the bore of the upper joint and the entry bore of the barrel match?

My understanding is that the exit bore of the barrel must not be larger than the entry bore of the top section. It can be equal or narrower.

My conjectural explanation is that you don't want the air column to hit an obstruction as it enters the clarinet itself. A barrel that ends equal to or narrower than the clarinet's entry provides a straight pathway into the clarinet. If the clarinet bore is narrower, the air flow is obstructed around the periphery and turbulence will result in the air column. But that's just a guess - someone with a stronger physics background might weight in with a different answer and explanation.

I do know that none of my working barrels have exit bores larger than the entry bore on my clarinets. As I remember, they're all narrower.

Changes or steps in the bore size between the barrel and top joint, in fact between any of the joints, introduces an extra acoustical impedance.

When done by the manufacturer it is usually an intrinsic part of the overall acoustic design. At least hopefully it is.

When introduced ad hoc by a player experimenting with things, then it's just "suck it and see"
If it works for you, that's fine.

I don't think it is possible for a third party barrel to be suitable for both Bb and A if the original barrels are not exchangeable.

Klose said." I don't think it is possible for a third party barrel to be suitable for both Bb and A if the original barrels are not exchangeable."
I have to disagree based on my professional experience. When I used my Bb and A clarinets for years I used Moennig and then Chadash barrels and would use the "proper" one on each. Many years ago I bought a Backun barrel for my Bb at one of the Clarinetfests after trying about a dozen and much to my surprise when I tried it on my A clarinet it not only sounded very good put played as well in tune as it did with the Chadash barrel. So for a few years I used the one barrel for both in my symphony and chamber works. Eventially I bought second one and found them interchangable. Conclusion, it depends on your clarinets, the barrel and your mouthpiece. The only golden rule for anything clarinet wise is try before you buy.

I still feel like I'm cheating when I use the same barrel for both, but it works fantastically, and is in tune!!

Plus the warmed up barrel is a benefit.

I agree with Dave. If it works, it works. Don't get bogged down by over thinking acoustical.concepts. I have "Bb" barrels that play great on my A's and vice versa.
