Who is the Yamaha YHR-871DU best suited for?

What is the effect of an unlacquered finish on a French horn?

An unlacquered finish on a French horn allows the raw brass to remain exposed rather than sealed beneath a protective lacquer coating. Many players feel this creates a more immediate, resonant response with a broader spectrum of overtones and a slightly more “alive” feel under the hands, though the tonal difference is subtle and highly subjective. Over time, the instrument develops a natural patina as the brass oxidizes, giving each horn a unique appearance that many musicians find aesthetically appealing.
