Product questions
Straight answers to the questions shoppers most often ask about this product.
No. Alto clarinet mouthpieces are noticeably larger. A Bb mouthpiece will sit loose inside this ligature and fail to hold the reed.
No. This is the ligature only. If you also need a cap to protect the reed in the case, buy one separately.
Barely. A ligature's job is holding the reed flat and consistent. Reed, mouthpiece, and embouchure drive tone far more.
Snug enough that the reed does not shift when you play. Past that you flatten the reed and choke the response.
