L'ouvrage propose une définition d'un métamodèle compositionnel combinant des arguments de la logique et de la linguistique cognitive et fournit un cadre pour analyser des compositions inspirées par la science. Une seconde partie délimite les pratiques créatives de A. Posadas, en se concentrant sur ses métamodèles fractals qui lui ont permis de composer la Liturgie fractale (2003-2007). ©Electre 2025
Metamodels in compositional practices
The case of alberto posadas's liturgia fractal
Many composers seem to find inspiration in science, although this fact is not standardized. Indeed, composers' musical practices are far from being homogeneous nowadays, and science has achieved an extreme degree of diversification, leading to a complex junction where both situations converge. This picture shows an impossible normalization spanning a wide range of factual compositional practices. Nevertheless, the common denominator to their scientific inspiration deserves musicological attention. We shall state, as a research hypothesis, that in spite of their obvious diversity a minimum of situations or stages stand out among creative processes shared by musicians who borrow scientific models when they compose. This hypothesis directly entails two research questions :
This book is aimed at providing some clues as to both questions. Its first part combines arguments from logics and cognitive linguistics, leading to the definition of a 'compositional metamodel'. It also provides a possible framework for analyzing science-inspired compositions. The second part of the book delimits Alberto Posadas's creative practices, focusing on his fractal metamodels - based on fractional Brownian motions, the Mandelbrot set, Lindenmayer systems and histologic fractals- for composing Liturgia Fractal (2003-2007).
