A sackbut is a type of trombone from the Renaissance and Baroque eras, characterised by a telescopic slide that is used to vary the length of the tube to change pitch. Unlike the earlier slide trumpet from which it evolved, the sackbut possesses a U-shaped slide, with two parallel sliding tubes, which allows for playing scales in a lower range .                                                                                                                                                                                                                                                                                                                                                                What is the Sackbut made of?                                                Sackbut. Musical instrument, the immediate predecessor of the modern trombone, made of thin, hammered metal, with a shallow, flat mouthpiece and a narrow, nonflaring bell. The instrument produced a soft sound that complemented the harpsichord, voice, viol, lute,recorder, and cornett.                                                                                                                                                                                                                       Where did the Sackbut come from?                                        Sackbut, (from Old French saqueboute: “pull-push”), early trombone, invented in the 15th century, probably in Burgundy. It has thicker walls than the modern trombone, imparting a softer tone, and its bell is narrower. The sackbut answered the need for a lower-pitched trumpet that composers of the time sought.                                                                                                                                                                                                                                                                                 What family is the sackbut in?                                                   The Sackbut belongs to the family of Woodwind instruments. The earliest form of slide trumpet, which afterwards developed into the trombone.
