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).
