All Yamaha marching instruments as well-balanced, so they are easy to hold maneuver while marching.
Hand-fitted valves and slides
Hand-fitted ensures an absolutely perfect fit and seal between the valve pistons and casing or slide parts. Such a fit helps to achieve smooth air flow and smooth action, and improves the response and intonation of thee instrument.
Laser-fused plasma-welded bells
A high-energy laser fuses the brass together for a virtually seamless bell, which results in continuous, even vibrations.
The perfectly rounded tubing results in less turbulence and a smoother air flow, thus making possible an excellent scale and reduced resistance.
All Yamaha marching instruments have heavy bracing throughout, so they are more durable at vulnerable points and can withstand the rigors of use in a marching band.
