Music Out Of Nothing A Rigorous Approach To Algorithmic Composition By Iannis Xenakis 1st Edition Peter Hoffmann by Peter Hoffmann instant download after payment.

This is the documentation and discussion of a research project in algorithmic computer music, started in August 1995 with a research in Paris, in the frame-work of a dissertation at the Technische Universit¨ at Berlin. Its scope is the latest achievement by Iannis Xenakis (1922-2001) in composing music with the com-puter at his institute CEMAMu (“Centre d’´ etudes de Mathematique et Automa-tique Musicales”1) in Paris. The composer called his new computer composition method “Dynamic Stochastic Synthesis”. It is a rigorous algorithmic procedure for not only composing the macro-structure of a composition (i.e. on the level of duration and pitch) but also the micro-structure of sound (i.e. on the level of the digital sample). GENDYN is the name Xenakis gave to his computer program(s) realizing the stochastic synthesis, short for the French term “G´EN´ eration DY-Namique”. The original program was written in BASIC by the composer himself at CEMAMu, Paris, with the assistance of Marie-H´ el` ene Serra. In 1991, a single run of this program, called “GENDY301”, generated GENDY3, a piece of about 20 minutes. It was later released on CD (NEUMA 450-86). In the aftermath, Xenakis tried to extend the program to include additional time-variant ef f ects by making some parameter settings of GENDYN’s stochastic processes time-dependent. This resulted in a second piece S709, premiered in 1994, which is beyond the scope of this study.
