The performance variations introduced by the musicians have been generalized into computational models in the KTH rule system. The models can convey gestural information about physical movement as well as emotional expression. The rule system was extended with new rules modelling metric, harmonic, melodic contour, and grouping accents as suggested by Parncutt (2003), and for interaction of rules. The accents are automatically rendered using a local shape of increased sound level and slower tempo around the accented note. We consider the rule system as a toolbox containing a set of general performance principles that to a certain extent have biological foundation. Then, the application of the rules depends on the intention, style, personal preferences, etc. We show how this can be done for three cases representing a music example from three different historical periods of piano music: baroque, romantic, and contemporary art music.

Keywords:   performance variations, KTH rule system, computational models, accents, metric, harmonic, melodic contour, grouping, classical piano music
