Abstract

From a musicological interpretation of the scientific notion of "modeling and simulation", this thesis presents an approach for computer-aided analysis where musical scores are reconstructed from algorithmic processes and then simulated with different sets of parameters from which neighboring variants, called instances, are generated. Studying a musical piece by modelling and simulation means to understand the work by (re)composing it again, blurring boundaries between analytical and creative work. This approach is applied to three case studies: an isolated technique, Pierre Boulez¿ (1925¿2016) Chord Multiplication, which was explored through the prism formed by the theories of H. Hanson, S. Heinemann and L. Koblyakov and by its computational implementation; the piece Spectral Canon for Conlon Nancarrow (1974) by the American composer James Tenney (1934¿2006) to which the computa- tional simulation from different sets of parameters was taken to its ultimate consequences when a "space of instances" is created and strategies of visu- alization and exploration are devised; and finally D ?esordre (1985), the first piano ?etude written by Austro-Hungarian Gyo ?rgy Ligeti (1923¿2006) in which the concepts of "combinatorial tonality" and "decomposition of a number (duration) into two prime numbers" were used to maximize the potential that a model has to produce different variations of the original piece (AU)
