Seminar at Speech, Music and Hearing:

Analysis of playing strategies in DJ scratching

Kjetil Falkenberg Hansen, TMH

Abstract

DJ scratching represents a skillful playing practice with complex musical output which have not yet been thoroughly studied. We describe some of the acoustical parameters of typical scratch improvisations, and also look at which musical parameters are typically used for expressive performance. Performance features from recordings of DJ improvisation were analyzed acoustically, based on gestures, and by regarding known scratch techniques and instrument characteristics. Extracted acoustical and performance parameters from the data give a first approximation on the functional ranges within which DJs normally play. Results from the analysis show that influential parameters found in other solo instrument performances have less impact in scratching; particularly pitch. There are indications that parameters commonly used for expressive communication, such as articulation and sound level, are disregarded for better control of other parameters. Some consequences the findings have on constructing models for scratch performances will be discussed.
