Sackbut Sackbut 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. Records of the term "trombone" predates the term "sackbut" by two decades, and evidence for the German term "Posaune" is even older. "Sackbut", originally a French term, was used in England until the instrument fell into disuse in the
Berlin Musical Instrument Museum Hotteterre. Curt Sachs, Director from 1919-1933, brought a scientific approach to the collections. He was one of the founders of modern organology (the study of musical instruments) and co-authored the Sachs-Hornbostel system of instrument classification. The Museum rose to international importance and his catalogs form the basis of academic research papers to this day. When the Nazis seized power in 1933, Sachs was dismissed from his post by the Nazi Party and forced to emigrate because he was Jewish. In 1935, the musical instrument collection was removed from the Academy to the new National Institute for German Music Research headed
