Who the YHR-871DU Double French Horn Is For

The Yamaha YHR-871DU is a professional F/Bb double French horn designed for players who want a Geyer-wrap instrument with a centered, dark-leaning sound and stable resistance from low to high register. The medium detachable bell with a relatively thick rim wire helps support a rich, deep tone with a solid core, while the 12.1 millimeter bore is chosen to maximize performance potential in demanding ensemble settings.

This model is particularly well-suited to orchestral, chamber, and studio players who value consistent response and clarity: a new gold brass leadpipe design promotes even blow and tone throughout the range, gold brass slide inner tubes emphasize tonal depth, and the rounded main tuning slide is shaped to provide ideal blowing resistance for this class of instrument. Ergonomic and practical features include an adjustable 4th thumb lever and pinky hook, plus a long pull ring on the Bb 2nd valve slide for convenient on-the-fly adjustments.

Common Questions About The Yamaha YHR-871DU

What type of wrap is the Yamaha YHR-871DU?

The YHR-871DU uses an orthodox Geyer-style wrap paired with a medium detachable bell, aiming for a rich, deep tone with a solid core and consistent resistance.

What is the effect of the unlacquered finish for the YHR-871DU?

The unlacquered finish on the Yamaha YHR-671DU French horn allows the brass surface to vibrate slightly more freely, which many players perceive as a subtly more open, resonant, and “alive” sound compared to a lacquered instrument. In practical terms, this often translates less into a dramatic tonal change and more into a difference in feel—players frequently notice increased tactile feedback and a more immediate response, making it easier to shape nuance and color. Unlacquered brass develops patina quickly, which some players embrace aesthetically.

Is the Yamaha YHR-871DU suitable for professional orchestral use?

Yes. The YHR-871DU is part of Yamaha’s Custom series and is built with professional-spec features including a gold brass leadpipe, gold brass slide inner tubes, nickel silver valve casing, string linkage, and a detachable bell for performance and transport needs.
