Musical Representations
The Musical Representations team explores the formal and dynamic structures of music and mobilizes them in creative environments for musical composition and interaction.
The Musical Representations team (RepMus) focuses on the structures of music (or “musical intelligence”) as they can be approached through computer science in order to analyze, formalize, represent, model, generate, and manipulate them, with the aim of providing broad support for musical creativity in contexts of composition, performance, improvisation, or analysis.
RepMus investigates representations at various scales, from symbolic structures to the signal level, ranging from epistemological and mathematical aspects to computational modeling and the development of technological tools widely used by musicians. These methods and tools apply to both written music and oral traditions, and to both classical and popular repertoires.
Research on high-level representations of musical concepts and structures—supported by the original programming languages and environments developed by the team—leads to the implementation of models that can be applied both to creative processes and to musical analysis. The exploration of interactive and/or synchronous time offers opportunities with new media for the development of real-time, interactive, open, collective, improvisational, and distributed works.
The tools and methods employed draw in particular on the following fields: musical formalization; tools for composition, analysis, performance, and improvisation; and involve formal computation, domain-specific programming languages, new notations, musical mathematics, creative AI and learning, computational (co-)creativity, and autonomous agents.
RepMus research is structured around three thematic areas:
- Theme (F)O(R)M: formal spaces, computer-assisted composition
- Theme REACH: human and artificial co-creativity, interaction
- Theme ECTIS: writing and control of interactive and synchronous time
The team has a long history of intensive collaboration with artists at the national and international levels. The three volumes of the book OM Composer’s Book document part of this work and ensure its international dissemination and long-term preservation.
