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-span reduction 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)].
