resembling a thimble, surrounds the lower part of the reed--this provides support for the lips and embouchure.

Since only a short portion of the reed protrudes past the pirouette, the player has only limited contact with the reed, and therefore limited control of dynamics. The shawm's conical bore and flaring bell, combined with the style of playing dictated by the use of a pirouette, gives the instrument a piercing, trumpet-like sound, well-suited for outdoor performances.
