Abstract: A mouthpiece for a musical wind instrument. The mouthpiece has a casing, a reed and a reed attachment assembly mounted in the top of the casing. The reed attachment assembly has a support member pivotably connected to a frame. The foot of the reed is clamped against a plate portion of the pivotable support member such that the blade of the reed protrudes from the attachment assembly and extends above the top surface of the casing with the tip of the reed being disposed proximate the leading edge of the casing. Means are provided for adjusting the inclination of the plate of the pivotable support member relative to the frame wherein the distance between the tip of the reed and the leading edge of the mouthpiece casing can be varied by the adjustment means.
