YAMAHA F Single Horn YHR-313. For those starting to learn the horn, I think it's best to first learn how to control the pitch with an F single horn, and then step up to a Bb horn and a full double horn to truly understand the instrument. How about this one for practice for elementary or junior high school students? It's an older model, but the lacquer is mostly intact and it's in good condition. The rotary valves and slides are in good working order, as shown in the photos. The original case is also included and is in good condition. If you are interested, please consider purchasing. Mouthpiece not included.
