Scratch (or scratching) is the musical art of rhythmically moving a vinyl record back and forth under a turntable's stylus while using a mixer’s crossfader or volume controls to shape percussive and melodic gestures.
Although often described as a technique, scratch developed into a recognizable musical style centered on the turntable as an instrument. Tracks and live routines foreground cut-up vocal phrases, drum hits, tones, and sound effects, arranged in time like drumming, with highly codified gestures (baby, transform, chirp, flare, crab, orbit, etc.). The result ranges from funky, danceable textures to virtuosic, highly percussive displays associated with DJ battles and turntablism.
