Project Confidently with a 10-Inch Bell

Yamaha uses precise laser-fused plasma-welding to join the bell for uniform vibrations and a seamless tone. The large bell aperture also gives this mellophone an open, free-blowing feel for expressive playability.

The leadpipe is made of gold brass for superior corrosion resistance and warn tone, while the tubing is pressure formed for smooth airflow and minimal resistance. Heavy-duty bracing throughout reinforces the mellophone's durability to handle the demands of marching band season after season.
