Common Questions About The Yamaha YHR-671DU Is the Yamaha YHR-671DU suitable for professional use? Yes. The YHR-671DU is built as a professional F/Bb double horn, with a design aimed at delivering smooth playability through all registers and updated mechanical details for performance consistency and reliability. What does a detachable bell change for the player? A detachable bell primarily improves portability and storage. It also allows easier packing for travel while keeping the playing characteristics of a medium-bell double horn. What is the effect of the unlacquered finish for the YHR-671DU? 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. We are proud to be an authorized Yamaha dealer
