Euphonium for dedicated low brass students.

Yamaha's YEP-321 Series 4-Valve Intermediate Euphonium is a premium euphonium that provides an ideal step-up for students ready to advance their skills. Featuring four top action pistons, a .571" bore, and 11" bell, the YEP-321S offers superior intonation and projection. Its handcrafted yellow brass body and bell produce a balanced, resonant tone that will inspire passionate performances. The small shank mouthpiece helps younger players achieve a centered, focused sound. Whether performing solo or in an ensemble, the YEP-321 Series is built to support years of progress.

Four Top-Mounted Pistons For Superior Intonation
The YEP-321's four compensating pistons provide accurate intonation throughout the euphonium's range, especially in the challenging lower registers. The additional tubing effectively solves the pitch issues inherent in three-valve euphoniums, allowing for resonant, in-tune performance across all octaves.

Large 11-Inch Bell Projects a Robust Tone
The YEP-321 Series features an 11", yellow brass bell that produces a quick response, wide dynamic range, and rich projection suitable for any performance setting. Students and educators will appreciate its resonant, balanced tone that blends well in ensembles while also shining in solo performances.

Durable Yellow Brass Body Built to Last
Yamaha's expert craftsmanship is evident in the YEP-321's handmade yellow brass body. Built to withstand the rigors of frequent use and travel, the durable yet lightweight body provides a resonant foundation for the instrument's impressive tone and projection. Its high-quality construction guarantees years of dependable performance for advancing students and amateur musicians.

Additional Features and Premium Touches
The YEP-321 also includes an ABS molded hardshell case for safe transport, as well as a Yamaha 48S small shank mouthpiece for comfortable playability and centered tone. Available in clear lacquer or silver plate finish, from the superior leadpipe to the robust bracing, every detail of the YEP-321 Series is designed to support progressing musicians in their musical journey.
