Top-performing mouthpieces for players of all skill levels

From an early age Vincent Schrotenbach displayed a natural aptitude for musical instruments and gravitated toward the trumpet during his teens. After emigrating from Vienna, Austria to the United States in the early 20th century, he performed professionally with ensembles including the Boston Symphony and the Metropolitan Opera before founding the Vincent Bach Corporation in 1918. For more than a century, Bach trumpet mouthpieces have been built on his commitment to innovation and careful craftsmanship. We now offer these iconic mouthpieces in a wide range of cup depths, diameters, and rim shapes to suit different playing styles — from the medium 7C, a dependable choice for students and beginners worldwide, to the larger 1C, favored by intermediate and advanced players seeking a reliable, versatile mouthpiece. Bach trumpet mouthpieces deliver the consistency and performance players expect.
