Sackbut eighteenth century; when it returned, the Italian term "trombone" became dominant. In modern English, an older trombone or its replica is called a sackbut. An older instrument generally differs from modern trombones by its smaller, more cylindrically-proportioned bore, and its less-flared bell. The bell section was more resonant (since it did not contain the tuning slide and was loosely stayed rather than firmly braced to itself). These traits produce a "covered, blended sound which was a timbre particularly effective for working with voices... zincks and crumhorns", as in an alta capella. The revived instrument had changed in specific ways. In
Sackbut the sources: it is either derived from the Middle French "sacquer" (to pull) and "bouter" (to push) or from the Spanish "sacar" (to draw or pull) and "bucha" (a tube or pipe). The term survives in numerous English spelling variations including sacbut, sackbutte, sagbut, shagbolt, sacabushe, shakbusse and shakbusshe. Closely related to "sackbut" was the name used in France: "sacqueboute" and in Spain, where it was "sacabuche". These terms were used in England and France until the 18th century. In Scotland in 1538 the slide instrument is referred to as "draucht trumpet" (drawn trumpet) as opposed to a "weir trumpet"
