Descrição
Comunicação apresentada na International Conference on Computational Models of Creative Cognition, Dublin, 1997. Music is one of the most intriguing and joyful
domain of research and analysis. Driven by this
insatiable curiosity, Musical Analysis has
emerged to formally understand and structure
music and its intrinsic intention and causality.
Each complete analysis of a piece points to
issues that go far beyond the normal graphical
music representation. A better analysis is
important not only to a better interpretation, but
also to a more perfect composition. An
exceptional composer is indeed an exceptional
analyst.
This paper presents a computational approach to
music composition through the use and
exploration of musical analysis. Centered on
Case-Based Reasoning and Planning techniques,
it consists on creating new solutions by keeping,
transforming and extrapolating knowledge from
already expert-made music analysis. For our
approach, each analysis is represented as a
precisely structured Case, divisible into all of its
components.
The process of composition we adopt is
progressive, left-to-right, and top-to-bottom and
has some similarities with (Wallas’ 1926) theory
for creative production (Macedo et al. 1996a)
which we adapted for this specifically structured
and complex domain.
The resulting implemented program has already
generated several different musical pieces, which
were examined and analyzed by experts, bringing
up precious questions and advice.
