This essay studies the relationship of audio signal processing and musical complexity, focusing on minimalistic electronic music. Minimalistic electronic music is a genre that builds on repeating monotonous music patterns, and is perceptually “low complexity” music. The song structure is often dependent on audio signal processing, used almost as a musical instrument to increase or decrease the intensity of the song. This essay investigates if audio signal processing might increase the perceived complexity of a low complexity music pattern (such as minimalistic electronic music). This is investigated by doing a literature review and a listening experiment. The literature review, which is on music history and musical complexity, showed that the evolution of minimalistic electronic music is correlated to the evolution of audio technology, and that it is likely that audio technological advancements has induced minimalist approaches to popular music production. The listening experiment was a modified MUSHRA-test where subjects listened to rhythmical patterns of various complexity, played with and without audio signal processing. Although few results could be verified with confidence intervals at α = 0.05, it could be concluded that there are tendencies of perceived complexity being increased by audio signal processing. Audio signal processing also seemed to have a greater effect on low complexity music than on music of higher complexity. This shows that there might be perceptive reasons behind the extensive audio signal processing in minimalistic electronic music.
