The 204M features a rich vibrant sound with excellent tonal projection. Yamaha R&D conducted extensive field tests with leading bands, and has redesigned the bracing for a more open 'free-blowing' feel.

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

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.Heavy bracing
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.
