By relaxing the embouchure and jaw, the tone becomes under-supported and unfocused. By tightening the embouchure and jaw, the pitch goes bright and loses the richness of its overtones. Unfortunately, by adjusting the embouchure, the brass player also alters the tone quality of their instrument. By relaxing the embouchure and opening up the oral cavity, the pitch will move flat. By firming up the embouchure and making the oral cavity smaller, the pitch will move sharp. The embouchure can be adjusted to address intonation issues due to tendencies of partials or fingering combinations. This creates the fullest tone, and serves as the target for each pitch.
Brass players refer to the center of a pitch, which is the point at which the embouchure is buzzing at the exact same pitch as the instrument is playing.
One of the challenges of adjusting pitch on brass instruments is that when adjusting pitch, the tone also changes. the trombone slide, adjustable valve slides on trumpet, 4th valves on euphonium and tuba, right hand in the bell of the horn), the embouchure serves as the primary method of intonation adjustment. While each instrument has unique ways to deal with intonation (e.g.
The valves, rotors, or slides serve to alter that fundamental pitch, but in the end, embouchure adjustment controls pitch at the macro level when moving between shelves and the micro level when adjusting intonation. As you have certainly noticed, pitch on brass instruments is primarily controlled by the embouchure.
