The single Bb horn has much the same advantage of lightness that the single F horn offers. Single Bb horns are highly prized by “high” hornists because they can make strenuous challenges in opera or concert that much easier. Typically, single Bb horns will be found in chamber music and solo situations (see Model 90).
The sound of Bb horns is lean and supple. The notes in the low register below low Bb can be successfully played with a fourth extension replacing the stopping extension, or better yet —as with Model 97—with a separate extra fourth extension.
Models 89 and 90 can also be ordered with an extra set of 3 valve slides and main slide that convert the instrument into an F horn.
- Thumb valve in A
- Stopping extension
