Did you know?

Like the trumpet, the cornet is a brass instrument with three valves, but its bore is somewhat more conical. Its range parallels that of the trumpet. It evolved in the 1820s, and its agility made it a very popular solo instrument. It often displaced the trumpet in 19th-century orchestras, and it preceded the trumpet in modern dance and jazz bands. Recent developments have made the two instruments very similar, and the cornet's popularity has waned considerably as a result.
