Whither Music?

Exploring Musical Possibilities via Machine Simulation

Project Summary

Vision

"Whither Music?" was the motto of Leonard Bernstein's 1973 Norton Lectures at Harvard ("The Unanswered Question"), where he analysed the musical developments that led to what he called the 20th Century Crisis of Music: the gradual decline of tonality, driven by a takeover of tonal ambiguity in the late 19th and early 20th centuries, eventually leading to complete abandonment of tonality in Schönberg's dodecaphony - a historical process that Bernstein portrays as equally inevitable and problematic.

WHITHER MUSIC? is a project that aims to establish model-based computer simulation (via methods of AI, (deep) Machine Learning and probabilistic modelling) as a viable methodology for asking questions about musical processes, developments, possibilities and alternatives - for music research, for didactic purposes, for creative music exploration scenarios. Computer simulation here means the design of predictive or generative computational models of music (of certain styles), learned from large corpora, and their purposeful and skilful application to answer, e.g., "what if" questions, make testable predictions, or generate musical material for further analysis, musicological or aesthetic. We believe that this would open new possibilities for music research, education, and for creative engagement with music, some of which will be further explored in the project.

Research Goals

This vision of purposeful application of computational models dictates the central methodological principles for our research:
veridical modeling and simulation require stylistically faithful, tightly controllable, transparent, and explainable models. These requirements, in turn, motivate us to develop and pursue a musically informed approach to computational modeling, as an alternative to the currently prevailing trend of end-to-end learning with huge, opaque neural networks. The cornerstones of our approach will be structured modeling (rather than end-to-end learning), multi-level and multi-scale modeling and structural projection (rather than note-by-note prediction), and exploiting musical knowledge (rather than purely data-driven inductive learning) at all levels - including the design of appropriately informed model architectures and loss functions.

Modeling Domains and Applications

In terms of modeling domains, we will be concerned with three types of computational models: models of music generation, of expressive performance, and of musical expectancy, mirroring the three major components in the system of music: the composer, the performer, and the listener.

In addition to developing fundamental machine learning and modeling methods, we will explore concrete simulation and application scenarios for our computer models, in the form of musicological studies, creative and didactic tools and exhibits, and public educational events, in cooperation with musicologists, music educators, and institutions from the creative arts and sciences sector.

At a fundamental level, the goal of his project is thus really two-fold: beyond developing the technology for, and demonstrating, controlled musical simulation for serious purposes, we wish to develop and propagate an alternative approach to AI-based music modeling, hoping to contribute to a re-orientation of the field of Music Information Research (MIR) towards more musically informed modeling - a mission we already started in our previous ERC project Con Espressione.

[And a final disclaimer, in case this is needed: of course we will not ever seriously attempt to look at Bernstein's Unanswered Question, and possible alternative paths that music could have taken, with computational methods. This only served as a grand motivation, and to give a name to our project.]
