clarinet pitched a fourth lower than the ordinary B clarinet, probably invented in about 1770 by A. and M. Mayrhofer of Passau, Bavaria. The name derives from its basset ("small bass") pitch and its original curved-horn shape (later supplanted by an angular form).

The boxwood instrument is usually built to order, in straight form with upturned bell
