Scratching performed by a DJ (disk jockey) is a skillful style of playingthe turntable with complex musical output. This study focuses on the description of some of the acoustical parameters and playing strategies of typical scratch improvisations, and how these parameters typically are used for expressive performance. Three professional DJs were instructed to express different emotions through improvisations, and both audio and gesturaldata were recorded. Feature extraction and analysis of the recordings are based on a combination of audio and gestural data, instrument characteristics, and playing techniques. The acoustical and performance parameters extracted from the recordings give a first approximation on the functional ranges within which DJs normally play. Results from the analysis show that parameters which are important for other solo instrument performances, suchas pitch, have less influence in scratching. Both differences and commonalities between the DJs’ playing styles were found. Impact that the findings of this work may have on constructing models for scratch performances arediscussed.
