The precise fit between valve casings and pistons after honing means no air leakage

Perfectly rounded tubing results in less turbulence and a smoother air flow, thus allowing for an excellent scale and reduced resistance.

A high-energy laser fuses the brass together for a virtually seamless bell which allows continuous even vibrations.

Hand-lapping valves and slides ensures an absolutely perfect fit and seal between the valve pistons and casing or slide parts. Such a perfect fit helps to achieve smooth air flow and smooth action and improve the response and intonation of the instrument.

All Yamaha marching instruments are well-balanced so they are easy to hold while marching.

All Yamaha marching instruments have heavy bracing throughout so they are more durable at vulnerable points and can withstand marching band.
