Historical Models

A number of different approaches have taken to computational modeling of musical expression:

• (Sundberg, 1988): A system of rules derived from, among other sources, the insights of musical performers. The rationale here is to assess the veracity of such intuitions by instantiating them as rules within an algorithm that can produce performances whose acceptability can be assesed.
• (Clynes, 1983): Acomplete theory of expression in a set of performance rules.
• (Todd, 1985,1989, 1992): Atheory of expression in algorithmic form but one in which the theoretical basis for the algorithm is grounded in observations from human performances.

The last method has the potential andvatage, for giving our desired results among others because it consists of an analysis by synthesis heuristic method.
