Bach flugelhorn mouthpieces have identical rims to their trumpet counterparts, but deeper, flugelhorn-style cups, a larger throat and backbore. The deeper cups produce a dark tone of lyric quality. Their fundamental component is intense; the upper partials are reduced to a minimum. Do not attempt to play flugelhorn with a refitted cornet or trumpet mouthpiece as you will be more likely to play out of tune and not get the rich sound characteristic of the flugelhorn.
Vincent Bach was a rare combination of artist and engineer. A mechanical genius and acclaimed trumpet soloist, his instruments and mouthpieces are used today in every major studio and orchestra in the world. Bach personally designed the tools and composed the plans that continue to set the high standards for making all Bach products today.
"Choosing the perfect mouthpiece is often more difficult than choosing the perfect instrument. Your success as a musician depends on the choice of equipment that will do justice to your capabilities."
