Bach Trumpet Mouthpiece - 3C, 5C, 7C

Vincent Bach's 7C, 5C, and 3C trumpet mouthpieces set the standard for excellence and playability over a century ago.

Bach trumpet mouthpieces continue that standard today through constant innovation and dedication to manufacturing trumpet mouthpieces. 

Because no two players have the same embouchure, what's perfect for one player may be entirely unsuitable for another. Bach produces thousands of combinations of rims, cups, and backbores so that players can find the best trumpet mouthpiece for their embouchure. 

You can play with confidence - Bach brasswind mouthpieces are lead-free.  Check the Bach trumpet mouthpiece chart below to see our most popular sizes.
