The history of Bach starts with mouthpieces. A century ago trumpet player Vincent Bach began experimenting with designs and manufacturing processes to replace a broken mouthpiece. Soon after Vincent Bach s mouthpieces and later his trumpets set the standard for excellence. Bach continues that standard today through constant innovation and dedication to the craft. In the Bach workshop crafting a mouthpiece begins with innovative yet classic designs and is then carved by a computer-numeric-controlled machine that shapes and cuts solid brass bars. Each step is precise within one ten-thousandth of an inch. A carefully selected Bach mouthpiece can help improve a player s embouchure attack tonguing and endurance. Because no two players have the same lip or tooth formation 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 mouthpiece for their individual embouchure.
