ASPECTS OF CONTROL AND PERCEPTION

This paper deals with the problem of artistic control in the performance situation and its effect on the perceived and experienced musical sound. This is not a presentation of controllers and control parameters, but a discussion in a wider framework where the description of variables and quantitative measures are emphasized. Models of human interaction in a live acoustical environment are mentioned and some results from MIDI performance analyses are presented. Perceptual issues concerning musical sound variables, visualization of sound attributes (time-varying models), analyses of musical sound, and subjective testing are discussed in the last part.
