Basset clarinet

Jovan Stosic December 31, 2021

The basset clarinet is member of the clarinet family similar to the usual soprano clarinet but longer and with additional keys to enable playing several additional lower notes. Typically a basset clarinet has keywork going to a low (written) C or B, as opposed to the standard clarinet’s E or E♭. The basset clarinet is most commonly a transposing instrument in A, although basset clarinets in C and B♭ and very seldom in G also exist. The similarly named basset horn is also a clarinet with extended lower range, but is in a lower pitch (typically F); the basset horn predates, and undoubtedly inspired, the basset clarinet.
