Pitch control

A variable speed pitch control (or vari-speed) is is a control on an audio device such as a turntable, reel-to-reel, tape deck or CD player that allows the operator to deviate from a standard speed (such as 33 1/3 or 45 rpm in the case of a turntable). The latter term "vari-speed" is more commonly used for tape decks.
