Who the BLASM Alto Saxophone Ligature Is For

The Bois BLASM Classique is a ring-style alto saxophone ligature for metal mouthpieces that holds the reed securely without screws while minimizing reed contact for efficient vibration. It is well suited to experienced players who want a fast, consistent setup and a more flexible response across the range; it is especially popular as an alternative ligature concept for jazz saxophonists exploring different articulation and resonance characteristics.

Unlike many traditional metal or string ligatures that rely on tightening hardware, the BLASM simply slips over the mouthpiece, and its inner O-ring helps protect the mouthpiece from scratches while providing a strong grip to reduce slipping. Because the ring design contacts mainly the reed edges and the back of the mouthpiece, many players choose it to encourage a freer-feeling reed and increased responsiveness.

Common Questions About The Bois BLASM

Will the Bois BLASM fit my alto sax mouthpiece?

The BLASM is intended for metal alto saxophone mouthpieces. If you are using a hard-rubber/ebonite mouthpiece or an unusually sized metal mouthpiece, confirm the exact mouthpiece model and dimensions before ordering.

How does a ring-style ligature differ from a traditional screw ligature?

A ring-style ligature slips on with no screw tightening, and it typically touches less of the reed. The BLASM is designed to contact the reed at the outer edges and the mouthpiece at the back, which can promote a more responsive feel and flexible tone for many players.

Does the inner O-ring do anything besides grip?

Yes. The inner O-ring helps protect the mouthpiece surface from scratches while also increasing friction to help prevent the ligature from slipping during playing.
