A technique employed by some DJs, consisting of the rapid back and forth movement of a record turntable to cause the pick-up to produce the rhythmic scratching sound that is characteristic of rap and hip hop. This is done manually, with the turntable drive disengaged, or on a special turntable made for the purpose. Many records now feature scratching as an integral part of the recording process, and some CD players are now available with facilities for scratching and other effects.
