Title: Meta-Plus: Stockhausen's Plus-Minus computerized and analyzed Institution: University of Amsterdam Begun: September 1993 Completed: November 1995 Abstract: Stockhausen's piece "Plus-Minus", composed in 1963, is analyzed and implemented into a computer program, called "Meta-Plus". Stockhausen's piece is an example of abstract composition, which has to be worked out first by the musician before she can play it. The hypothesis is twofold: (1) that formalisation and implementation is an appropriate way of analysing "Plus-Minus" and comparable meta-musical pieces; (2) that Stockhausen's "Plus-Minus" is a piece which examplifies a specific method of composition which can be formalised. The purpose of the computer program is twofold: (1) to provide musicians, who want to make a version of Plus-Minus, with a user-friendly tool to manage this task; the program asks for the input of parameters, and calculates a structure according to the rules of Stockhausen; its output can be either a MIDI-file, a score or a sound-file; (2) to provide the musicologist, who wants to analyze Plus-Minus, with a tool with which she can study its formal description, as well as create as many versions as possible with different parameter settings. The research focusses on two questions: (1) - a musicological issue - what is the musical identity of Plus-Minus; (2) - an AI issue - what kind of composition is modelled in Plus-Minus, and what can be learned from this (Stockhausen's) method for more generalized composition models.
