Programs and "programs" for sequential patterns in motor behavior.

Abstract Sequences of discrete movements that are relatively slow offer a problem of temporal structure to the brain. Some attempts to analyze the structure of such tasks as finger tapping and producing rhythmic sequences are discussed. In general the available models have dealt with temporal behavior in a strictly serial fashion. More recently higher-order structural aspects have become accessible. As an illustration of this approach the analysis of a piano composition of Erik Satie, Vexations , is discussed.
