Collection: C. G. Conn Euphonium Mouthpieces

About Shank Size/Selection

The shank is the part of the mouthpiece that fits into the instrument. Choosing the correct shank size is important because a mouthpiece must match the receiver of your instrument to fit and play properly.

A mouthpiece made for trombone, euphonium, or baritone will physically fit any instrument that uses that same shank size.
