Schilke 51D Large Shank Trombone & Euphonium Mouthpiece
The premier standard for massive tonal core, orchestral warmth, and euphonium resonance.
The Schilke 51D Large Shank is universally celebrated across the brass community as the quintessential mouthpiece for euphonium artists and large-bore tenor trombonists seeking a deep, singing, and dark orchestral voice. Renowned for its distinctive, voluminous "D" bowl-shaped cup, this mouthpiece provides exceptional air volume capacity, allowing musicians to produce an immense, room-filling sound with a rich fundamental core and velvety overtones.
Engineered to fit standard .547" large-bore tenor trombones and modern compensating euphonium receivers, the large shank 51D pairs a 25.55 mm inner cup diameter with Schilke’s "J" (.277") throat. This internal geometry optimizes airflow and backpressure, ensuring that low and middle registers speak with authoritative weight while the upper tessitura retains warmth, stability, and pitch security without thinning out. The standard Schilke rim profile delivers optimal comfort and endurance for demanding symphonic, brass band, and solo repertoire.
