sackbut

n. medieval wind instrument resembling the trombone; (Biblical) ancient stringed musical instrument

The Sackbut (var. Sacbutt; Sackbutt; Sagbutt;), a brass instrument from the Renaissance and Baroque Eras, is the ancestor of the modern trombone. The name is derived from the Middle French sacquer and bouter ("push" and "pull") and the term survives in numerous English spelling variations including sacbut, sagbut, shagbolt and shakbusshe. In France, the instrument was called sacqueboute; in Germany, Posaune, and in Italy, trombone. The term sackbut is usually used to differentiate the historic instrument from its modern counterpart. Increasing interest in authentic performance in recent years has brought many trombonists to the sackbut.
