Maurice Benterfa (1937–2018) influenced generations of musicians with his unique approach to brass pedagogy. His Site des vibrations concept applies to all brass players, from beginners to professionals, focusing on sound perception and control.

Behind the apparent simplicity of his exercises lie fundamental principles for developing confidence in sound production and achieving consistent quality across the entire range, while also improving endurance. However, their true effectiveness depends on how they are practiced: absolute concentration and precise visualization of the Site des vibrations are essential to fully reap their benefits. By fully engaging in this state of sound awareness, each musician refines their technique and gains greater ease.
