 A true euphonium sound with clear highs and clean tone. This mouthpiece was originally designed by Denis Wick for the best-selling Yamaha 321 euphonium, and features a small shank with a medium bore and open backbore. The first 6BYs were made with a slightly smaller shank than the normal S fitting to help the response and intonation of the 321, but the 6BY is now made with a standard S shank. It is related to the 6BS trombone mouthpiece but at 7.12mm, has a larger bore than the 6BS, which has a bore of 6.66mm. It is a perfect match for the Yamaha 321 and ideal mouthpiece for young band musicians and players seeking a clear, resonant sound.

Cup diameter: 25.4mm.
Rim width: 6.26mm.
Throat: 7.12mm.
Backbore: Medium. Small shank.
