A bold sousaphone built for powerful projection.

The Yamaha YSH-411WC Series Brass BBb Lacquer Sousaphone delivers an impressively rich tone suited for marching bands and orchestras alike. Handcrafted with care, its brass body and bell provide resonant sound that carries for all to hear. You'll appreciate the instrument's noiseless valves and slides, as well as its heavy bracing and rounded tubing that make playing feel effortless while standing up to the rigors of regular use. The included 67C4 brass mouthpiece offers versatile sound that can achieve a mellow warmth or bold power. When it's time to head to your next performance, pack up the YSH-411WC Series in its wheeled case for easy transport.
Hand-lapped Valves Ensure a Seamless Performance
Yamaha hand-laps the valves and slides of the YSH-411WC Series for an airtight fit that allows air to flow freely without obstruction. The result is responsive action and noiseless playing so you can focus on your music rather than distracting squeaks or resistance. Marching sousaphone players will especially appreciate valves and slides that move easily and don't require excess effort.

Rounded Tubing Reduces Resistance for Smooth Playability
The YSH-411WC Series features rounded tubing that allows air to flow smoothly through the instrument. Less turbulence means less resistance so you can play with greater ease and comfort. The tubing's shape also helps produce an excellent scale and centered pitch for superior intonation. Whether you're playing low notes or high, each one sings with clarity.

Heavy Bracing Adds Structural Durability
Yamaha reinforces the YSH-411WC Series at critical stress points with heavy bracing. The bracing helps prevent dents, dings and other damage that can occur from regular use or accidental bumps and drops. Band directors will appreciate an instrument built to withstand the demands of marching and practice. The bracing also contributes to the sousaphone's resonance by allowing it to vibrate freely as you play.

Included Accessories Provide Versatility and Protection
The YSH-411WC Series comes with several useful accessories to help you get started. Its 67C4 brass mouthpiece offers an all-around versatile tone that pairs well with the instrument's rich sound. You'll also receive Yamaha valve oil to keep the valves moving smoothly, as well as a wheeled case for safe storage and transport between rehearsals, performances and storage. The case's wheels make it easy to roll the sousaphone around without straining your back.
