The Basset-Horn is not a horn at all, but a member of the clarinet family. It is larger than the conventional clarinet and plays lower notes. Though composers no longer write for it, the basset-horn was very popular during the late 18th and early 19th centuries and it was one of Mozart's favorite instruments. Early models were curved ; by the 1780s, the tube had been given a distinctive "kneejoint" shape as shown here.

| And also... |
| To enable the basset-horn to reach its lowest notes, early models of the instrument had a "box" or "book" at the lower end of the tube. Inside, an extra length of tube zig-zagged its way through before emerging into a metal bell. |
