Bach Small Shank Tenor Trombone Mouthpiece
Vincent Bach trombone mouthpieces set the standard for excellence and playability over a century ago.
Bach trombone mouthpieces continue that standard today through constant innovation and dedication to the manufacture of brass instrument mouthpieces.  Check the Bach trombone mouthpiece chart below to see our most popular sizes.
Because no two players have the same embouchure, what is perfect for one player may be entirely unsuitable for another. Bach produces thousands of different combinations of rims, cups, and backbores so that each player can find the best trombone mouthpiece for their individual embouchure.
You can play with confidence – Bach trombone brass mouthpieces are lead-free.
