Flat LeBlanc

Hello!!!

I have a dilema. I play a LeBlanc Opus and a Buffet R-13. My intonation on the R-13 is pretty good, with the exception of the altissimo (at about the Eb above the staff). On my Opus, however, my pitch begins sagging at top space G. When inspecting both clarinets it appears that the register vent tube on the Opus is placed higher up on the upper tenon than the R-13. Could this be causing me to play flat? I played both back-to-back and the flatness presents itself in the same place each time on both horns, so I don't think I'm changing anything. Any thoughts???

Thanks!!!
Clayton

Edit: On the R-13, I play a 66mm barrel, and my intonation is pretty good. However on the Opus I am forced to play a 65mm barrel, and I'm still a tad flat in the upper register. Thanks!!!

Are you, by any chance, using a Vandoren 13-series mouthpiece? If so, it is highly likely to play flat. I play a Leblanc Concerto (same acoustic design as the Opus) and it plays in tune at A=440 with a 66mm barrel pulled slightly, or a 67mm pushed fully home, with a Vandoren M15 NOT 13-series.

If there are so many people on this board unwilling or unable to have a civil and balanced discussion about important issues, then I shan't bother to post here any more.

To the great relief of many of you, no doubt.

I play a custom mouthpiece (same one) on both horns.

I guess what I'm trying to ask is, on different horns, do some of you find it necessary to play different sized barrels. Is this due to the design of the instrument (please see my above comment on the register vent tube placement) or is it because of the formation of your oral cavity?

Thanks!!!

I play on a Leblanc LL and found middle B and up to be on the flat side (this was using a regular B40). However, the worse part was that everything below that was VERY sharp. This has caused me many embarrassing situations.

A very reputable player in my area selected an M15 13series for me to try. I was skeptical about the 13 series because I didn't want to be any flatter. To my surprise this M15 brought my lower notes down and didn't do anything to the rest of the horn. In short, the M15 13series put my clarinet in tune with itself. I can now play in all registers without making any embouchure adjustments. I purchased it from him and have been playing on it ever since.

It is the summer so the real test will be when the Winter months come.
