 Chadash Barrels
Author: Phurster

A few months ago I bought a couple of Chadash Barrels. I have been very pleased with the results on my RC prestige. I got a 66mm for the Bb and a 65mm for the A. I noticed recently that the 65mm barrel was stamped B 65.

Is there a difference in the bores with B and A barrels?

If it sounds ok should I worry about any differences?

Thanks Chris.

Yes.


No...with two explanations.

Many clarinetists find that the smaller amount of overall air "volume" in the A barrel (due to the smaller dimensions) makes up in some way for an over sized bore area in their Bb's.

The similar phenomenon is true in the case of the larger bore Bb barrel making up for an area inside their A clarinet that has shrunk.

Then there's the second category of use-whatever-works-best no matter the equipment.

I kind of like the second category best. : ^)

So, a 65mm Bb Chadash barrel has MORE volume than a 65mm A Chadash barrel? Would this imply a different taper between the A and Bb barrels, too,?

"The similar phenomenon is true in the case of the larger bore Bb barrel making up for an area inside their A clarinet that has shrunk."

Are you speaking mainly about improving sound and resistance, or tuning?

Yes and yes.

Starting with Hans Moennig of Philadelphia over 3/4's of a century ago, this was the intent of his inverse taper. He made all barrels for new instruments from scratch on an old belt-driven lathe.

Reverse tapers improve the tuning of the 12ths (especially throat E - B & F - C in particular) for both the shorter tube Bb clarinet and the longer tube A clarinet.

Whether it improves sound and gives you the resistance that you are after is completely subjective. Tuning ratios between registers are less subjective.

My experience with the Buffet/Chadash is that it feels very slightly more resistant at first and provides more focus and beauty to the sound. But the *kind* of "resistance" felt at first blush dissipates quickly.

Once I became accustomed to the very tiny change in the type of perceived resistance and made an extremely slight adjustment in the way I shape the air into the clarinet, and with an extremely slight alteration in reed selection and reed preparation, I realized that the barrel simply shaped the sound differently - with much more inherent capacity for glow, ring, or luminosity to the sound.

What Greg Smith said!
I agree, adding that the taper, while originally designed to correct the inherent tuning flaws of certain clarinets*, also causes a reflection of the waves so as to change the coloration.
Such palette changes can enforce the fundamental, while others seem to add overtones. This effect can be augmented depending on how the taper is rendered.

That being said, some players prefer a wider entrance to the A-barrel (0.592 or more) than on the Bb (0.590), while others follow Greg's formula. This is why it is worth trying multiple barrels or various configurations.

As for using one barrel for both....why not? IF it works well for you.

Disclaimer: I make barrels.

*Keep in mind that Hans substituted a barrel one mm longer, and took 1mm off of the bell joint. Since that era, clarinet makers have changed configurations, so the adjustments need not be so drastic.

Thanks for the expert replies. When I have money I will try an A 65 just in case it helps.

Thanks Chris.
