Schilke 69C4 Tuba Mouthpiece

Versatility, Comfort, and Reliable Performance

The Schilke 69C4 is one of the most versatile tuba mouthpieces in the Schilke Standard Series. Originally developed for a prominent West Coast tubist, the 69C4 departs from the traditional deep Helleberg design in favor of a medium-depth cup and a wide, comfortable rim that deliver exceptional flexibility, secure response, and dependable performance in virtually every musical setting.

Designed to provide an ideal balance of warmth, clarity, and efficiency, the 69C4 responds quickly throughout the instrument's range while maintaining a focused tonal core and excellent projection. Its forgiving design makes it equally well suited for orchestral performance, wind ensemble, chamber music, commercial playing, and solo literature.
