A Bach Mouthpiece, Heir to a Benchmark Expertise
Since 1918, Vincent Bach has built his reputation by combining musician's demands with engineering precision. The Commercial series follows this tradition: a mouthpiece designed to meet modern projection needs while maintaining a "classic" design foundation characteristic of the brand.
For Which Trumpeter and Styles?
This mouthpiece is aimed at intermediate to professional musicians who want to gain sonic presence without sacrificing stability. It is particularly suitable for contexts where one needs to "cut through": jazz, pop, wind orchestra, brass band, and all amplified or very dense playing situations.
Sound and Design
The cup (internal shape influencing the timbre) with a modified V shape promotes a broad sound and good hold in the upper register. The rim (contact area), medium wide and slightly flatter than a standard 7C Bach, stabilizes the attack. The throat (internal taper) and the backbore (insertion part) are calibrated to preserve projection and ease of blowing.
Recommended Compatible Accessories
For daily protection: mouthpiece case/pouch and mouthpiece cleaning brush.
