Alliance Brass David Childs DC3M Signature Euphonium Mouthpiece

Developed in collaboration with internationally renowned euphonium soloist David Childs, the Alliance Brass DC3 is a professional large-shank euphonium mouthpiece designed for players seeking a rich, centered sound with exceptional flexibility throughout the register.

The DC3 is the model David Childs himself uses on euphonium, in a gold-plated finish, and has also been the mouthpiece of choice of renowned euphonium artist Robert Childs.

With its 26.00 mm cup diameter and deep cup, the DC3 provides the breadth and resonance expected from a serious euphonium mouthpiece while retaining clarity, response, and control. Its carefully balanced design allows the player to produce a warm, expansive tone at softer dynamics while maintaining focus and projection as the volume increases.

The 7.45 mm bore provides a free-blowing feel with plenty of capacity for a full euphonium sound, making the DC3 particularly well suited to advanced, professional, brass band, solo, and orchestral playing.
