All Brass “Buzzing Rim” — Trumpet / Horn Embouchure Visualizer

The All Brass Buzzing Rim is an embouchure visualizer designed for trumpet and horn players who want a clearer look at how their lips are actually functioning while buzzing. Rather than a full mouthpiece, this practice tool isolates the rim so players — or their teachers — can directly observe lip placement, aperture, and movement. It’s a straightforward diagnostic aid for identifying embouchure problems that are hard to see or feel from the player’s own perspective, making it a useful addition to a practice routine or teaching studio alongside a standard mouthpiece.
