ANDRÉ RIOTTEFormalisms and the freedom of imaginationAbstractIn margin of the post-serialism, the XXth Century European music-theoretical approach developed a powerful idea of formalization, particularly in France. Based on a new conjunction of mathematics and music, this movement gave rise to several tools, often translated into data-processing software. Among the emergent models, beside the stochastic approach, the topic of number periods which are relatively primes led to the development of formal instruments like the Partition of Residual Classes (PCR), joining together Set Theory and Sieve Theory, suited to the formalization and the production of non-repetitive scales as to the complex polyrhythms. As a composer, the author used this application through several of his 17 Inventions for piano (1988-1989) ; he outlines of other European developments in the same way, and concludes by the necessary distance, for the composer, between his freedom and the formalisms he works with. |
