Bass clarinets also exist in other keys, notably C and A, but are very rare (in contrast to the regular A clarinet, which is quite common in classical music). Bass clarinets regularly perform in orchestras, wind ensembles/concert bands, occasionally in marching bands, and play an occasional solo role in contemporary music and jazz in particular. There is an even lower-pitched clarinet called the contrabass clarinet, and a slightly higher-pitched clarinet (but lower-pitched than a Bb soprano) called the alto clarinet. Someone who plays a bass clarinet is called a bass clarinetist.
