Scratching (DJ technique)

Technique and equipment

At its simplest, scratching requires a platter that can be manipulated by hand, a cartridge and stylus to read grooves, and a mixer with a responsive crossfader. Modern setups may use traditional vinyl, direct-drive turntables, or digital vinyl systems (DVS) that control digital audio with a vinyl-like control record. Key elements include slipmats to reduce friction, a sturdy tonearm, and a mixer whose crossfader can be adjusted for quick cuts.

• Common gear: turntable or DVS, slipmat, cartridge/stylus, DJ mixer with crossfader.
• Basic motions: forward and backward pushes, controlled releases, and coordinated fader cuts to sculpt sound.

There are many named scratch techniques, each producing a distinct timbre or rhythmic result. Typical examples include the baby scratch, forward scratch, transform, chirp, flare and crab. These techniques are often combined into longer routines and can be practiced on specific sample records designed for scratching.

History and cultural impact

Scratching emerged in the mid-1970s as DJs experimenting with breaks and sounds in block parties and early hip hop events. A few pioneering DJs are often credited with discovering and popularizing the method in live settings; over time scratching became a signature element of hip hop performance and production. By the late 1980s and 1990s it had also been assimilated into rock-influenced styles such as rap rock, rap metal and nu metal, where DJs contributed texture, riffs and rhythmic punctuation.

Scratching is both a studio tool and a live art form. In recorded music it is frequently used to create memorable sampled hooks and bridges; in performance it allows DJs to improvise solos or to add percussive layers to songs. The level of technical skill involved led to formal competitions—most notably the DMC World DJ Championship and events organized by the IDA—where turntablists are judged on creativity, technique and musicality.

Scratching is distinct from beat juggling: scratching focuses on sound articulation by moving a single record back and forth, while beat juggling rearranges and repeats rhythmic material using two records or channels. Today scratching continues to evolve, with artists blending analog touch with digital effects and controllers, and with educational resources that treat the turntable as a legitimate musical instrument and performance medium.
