About The Yamaha YSH-411S Sousaphone - Silver Plated

The 411 Sousaphone features a brass body and bell for an incredibly rich almost orchestral sound. The bell front design enhances tonal projection, while the intonation is state-of-the-art. Players will appreciate the securely centered notes and easy playability, while band directors will value its durability.


  • Extra mouthpipe bit - The 411 features specially designed bits for comfortable mouthpiece positioning.
  • Well balanced - Yamaha Sousaphones are extremely well-balanced, easy to hold while marching.
  • Heavy bracing throughout - Because the Sousaphone is for use in a marching band, it has heavy bracing throughout to make it more durable at the vulnerable points.
  • Pressure formed tubing - Perfectly rounded tubing results in less turbulence and a smoother air flow, thus allowing for an excellent scale and reduced resistance.
