Comfort and durability compliment the smooth action of this professional tuba.

The 641 professional Bb tuba features a rotary valve configuration for a traditional Teutonic sound with the kind of precise intonation and easy playability only made possible by modern engineering expertise. It is characterised by a warm dark sound with an abundance of tonal colours.

Hand-lapped rotary valves

Hand-lapping is a time-consuming finishing process which results in superior valve fit for noiseless, responsive action and easy tone changes.

Hand-lapped slides

Hand-lapping achieves the perfect balance between airtightness and smooth action.

Nickel-silver spatula keys

Carefully positioned nickel-silver spatula keys are strong and are capable of comfortable fast fingering.

Ball joints for rotary valve levers

The Yamaha-developed ball joints for the rotary valve levers are durable, yet achieve silent operation and light action.


The long leadpipe contributes to a beautiful, dark, smooth tone which blends well with other instruments.

Tuning slide position

The careful positioning of the tuning slide makes it easier to adjust the slides while playing.
