Abstract

Because of its minimalist construction, Steve Reich’s Clapping Music provides an ideal crucible for an examination of the role of expressive timing and expressive timbre in musical performance. Seven recordings of Clapping Music are studied. The analysis begins by dissecting the seven performances into hundreds of segments that contain either single handclaps or double handclaps. These are then studied in many ways: the consistency with which performers are able to maintain the timbre of their claps, the height percept of a handclap and its meaning for such a percussive sound, the accuracy in time with which performers can maintain a steady pulse. When clapping together, the timbre of the clap pair is dependent not only on the individual timbres but also on the timing of the claps. It is possible to measure the accuracy in time with which performers synchronize the double claps. The section-by-section timing deviations correlate significantly with a simple measure of complexity: the more complex the pattern, the greater the timing deviations.
