Yamaha YEP-321 Intermediate 4-Valve Euphonium

Honed valves

The precise fit between valve casings and pistons after honing means no air leakage.

Pressure formed tubing

Perfectly rounded tubing results in less turbulence and a smoother air flow, thus allowing for an excellent scale and reduced resistance.

Laser-fused pluzuma welded bell

A high-energy laser fuses the brass together for a virtually seamless bell, which allows continuous even vibrations.


The excellent intonation of the YEP-321 helps to foster a feel for correct pitch in beginning players.


The responsiveness of the YEP-321 assists beginning players in learning the phrasing of the euphonium.

Available feature

The YEP-321 euphonium is available with a silver-plated finish.
