Rhythmogram analysis of human and synthetic performance

Previously, a method of performance analysis has been described which is based on a multitimescale decomposition of the acoustic signal [Todd, ‘‘Wavelet analysis of rhythm,’’ J. Acoust. Soc. Am. 93, 2290(A) (1993)]. This analysis is sensitive to a variety of expressive devices employed by musical performers including tempo, dynamics, and articulation. The output of the analysis is a ‘‘rhythmogram’’ which resembles the time-spanreduction of the theory of Lerdahl and Jackendoff. In this paper, the results of some analyses of real and synthetic performances are presented [Todd, ‘‘The dynamics of dynamics: a model of musical expression,’’ J. Acoust. Soc. Am. 91, 3540–3550 (1992)].
