Scratching is a DJ or turntablist technique used to produce sounds for some types of music. It was originated by Grand Wizard Theodore, an early hip hop DJ from New York (AMG). Theodore developed scratching from DJ Grandmaster Flash, 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) Kool Herc was also an important early figure. The technique is designed to accentuate the work of the DJ by creating an assortment of sounds through the rhythmic manipulation of a vinyl record, and has spread from hip hop music to a number of other musical forms. Within hip hop culture, scratching is still of great importance in determining the skill of a DJ, and a number of competitions are held across the globe in which DJs battle one another in displays of great virtuosity. In recorded hip-hop songs it is common to have a scratched hook where lines from different rap songs are scratched in succession.
Almost all scratches are produced by moving a vinyl record back and forth with the hand while it is playing on a turntable. This creates a distinctive sound that has come to be one of the most recognizable features of hip hop music. Ideally, scratching does not damage a record because the needle stays within the groove and does not move horizontally across the record's surface. The basic equipment setup for scratching includes two turntables, and a mixer with a crossfader. When scratching, this crossfader is utilized in conjunction with the "scratching hand" to cut in and out of the scratched record. CD players and computer hardware/software combinations have emerged which allow DJs to produce scratch sounds without vinyl records by manipulating digitally recorded sounds.
