a wind instrument. The bassoon, formed by a U-shaped conical tube ending in a bell, consists of four parts. Sound is produced by a double reed attached to an S-shaped metal tube, which connects the reed to the bore. The bore contains 25–30 side holes, five or six of which are covered by the fingers and the rest by keys. The instrument has a range from B b below the bass staff to D or F at the top of the treble staff.
The bassoon was developed in Italy in the 1520’s and 1530’s and was introduced into the symphony orchestra in the mid-18th century. It is used in symphony orchestras, which generally have two or three, sometimes four, bassoons, in wind orchestras, and in other ensembles; it is also used as a solo instrument. Music for the bassoon is written mainly in the bass and tenor clefs. Of the other varieties of bassoon, only the contrabassoon is widely used.
