Scratching

Scratching, sometimes referred to as scrubbing, is a DJ and turntablist technique used to produce distinctive sounds by moving a vinyl record back and forth on a turntable while optionally manipulating the crossfader on a DJ mixer. While scratching is most commonly associated with hip hop music, since the mid-1970s, it has been used in some styles of pop and in nu metal. Within hip hop culture, scratching is one of the measures of a DJ's skills, as in DMC World DJ Championship or IDA (International DJ Association) former ITF (International turntablist Federation) where the DJs can use only scratch oriented gear (turntables + mixer + digital vinyl systems or vinyl only), and there are many scratching competitions.

In recorded hip-hop songs, scratched hooks often use portions of other songs.

History

Scratching was developed by early hip hop DJs from New York such as Grand Wizard Theodore, who describes scratching as, "nothing but the back-cueing that you hear in your ear before you push it [the recorded sound] out to the crowd." (Toop, 1991). Jamaican-born DJ Kool Herc also influenced the early development of scratching. Kool Herc developed break-beat DJing, where the breaks of funk songs—being the most danceable part, often featuring percussion—were isolated and repeated for the purpose of all-night dance parties.

Damping (music)

Damping is a technique in music for altering the sound of a musical instrument. Damping methods are used for a number of instruments.

Guitar

On guitar, damping (also referred to as choking) is a technique where, shortly after playing the strings, the sound is reduced by pressing the right hand palm against the strings, right hand damping (including Palm muting), or relaxing the left hand fingers' pressure on the strings, left hand damping (or Left-hand muting). Scratching is where the strings are played while damped, i.e., the strings are damped before playing. The term presumably refers to the clunky sound produced. In funk music this is often done over a sixteenth note pattern with occasional sixteenths undamped.

Floating is the technique where a chord is sustained past a sixteenth note rather than that note being scratched, the term referring to the manner in which the right hand "floats" over the strings rather than continuing to scratch.

Skanking is when a note is isolated by left hand damping of the two strings adjacent to the fully fretted string, producing the desired note (the adjacent strings are scratched). The technique is especially popular among ska, rocksteady and reggae guitarists, who use it with virtually every riddim they play on.
