Featuring a 0.728″ bore and a 17.5″ bell, the YBB-321 produces a warm, focused tone across all registers. Its 4-valve, upright piston configuration provides a familiar feel for those transitioning from a beginner horn.

The YBB-321WC’s 4-valve design helps maintain intonation throughout the tuba’s range, including tricky low notes.

The wide bell also contributes to an open, responsive blow that encourages good breath support and control.

Constructed entirely of yellow brass, the YBB-321 provides a balanced timbre and durable build quality to last through years of regular use. Its lacquered finish protects against tarnish and wear while subtly influencing the overall tone. Schools and individuals can depend on this tuba to serve students well into their advancing skill levels and beyond.As with all Yamaha instruments, the YBB-321 tuba reflects the brand’s commitment to high quality, innovative design, and passion for music.
