Reference Notes
The benchmark dark orchestral tuba mouthpiece. 33mm diameter with a deep funnel cup lowers the Helmholtz resonance frequency, producing a massive fundamental-rich sound essential for Mahler, Bruckner, and Strauss. Use these measurements as a comparison starting point: fit and response still depend on the player, dental structure, instrument receiver, and each manufacturer's measuring method.
