The upper joint body is drilled out slightly larger, where a thin ebonite pipe with an oboe bore is adhered. Ebonite is an excellent material for wind instruments. Much knowledge was derived from our own bassoon manufacturing, and with further engineering, Yamaha successfully developed oboes with reliability and the warmth of wood.

Toneholes

Every tone-hole (except metal octave vents) is lined with POM resin for air-tight, stable contact between each pad. In the rare event that the wood should crack, the damage to the tone-hole profile and intonation would be minimal thanks to the inserts.

Engraving

The trademark logo is engraved on the back of the upper joint.
