Am I the only one that thinks there should be a "Barrels" sub-section here? But that's not the main point, the main point is, I just ordered my 5th Bb clarinet barrel today. Geeze. It is the Clark Fobes 66mm. Not a cheap endeavor. My other barrels are in order of purchase: 1. Original Buffet R-13 Greenline barrel 66mm 2. Buffet Moennig barrel 65mm 3. Clark Fobes barrel 64mm 4. Clark Fobes barrel 65mm 5. Clark Fobes barrel 66mm (en route) The first two Clark Fobes barrels I got were during the show "Urinetown" at Temple University, when I just couldn't seem to reach the pitch of the piano. I didn't have a good tuner at the time, but now realise just how poorly tuned that piano was. Anyhow, with my new Peterson Stroboflip tuner (and I highly recommend this tuner to everyone if they ask) I realize that even with the 65mm I'm playing quite sharp, so we come to the need for my 5th barrel. I guess I'm gonna keep all these other barrels as well, to have an arsenal in case some singer feels the need to belt "It's a Privelige to Pee" or some equally mind provolking number at a=447 while the reed section's lips bleed and those in the audience with hearing aids shout "Oh the humanity!" The joys of doubling.
