Abstract – Music is a pervasive cultural artefact that has persisted in part because of its ability to elicit a wide range of perceptual and physiological responses.

Music expressivity is the means through which performers elicit responses from listeners. The nature of music means that many expressive aspects of music can be represented mathematically, quantitatively as data, which makes it amenable to computational modeling and analyses. It is the shaping of music’s sonic properties that conveys structures, affect, and meaning. I shall describe some of the ways we can capture this expressivity and show visually the structures they convey.

Next, I will demonstrate that recordings of cardiac arrhythmias, the result of the electrical conduction system of the heart gone awry, possess properties similar to expressive music. Finally, the brain and autonomic nervous system are known to influence cardiac electrophysiology and its propensity for arrhythmias. Here, I will describe our study on cardiac response to live music performance, and how quantifiable aspects of music expressivity and cardiac behaviors can be exploited to investigate heart-brain interactions. I shall also introduce our work on music therapeutics with physiological feedback.

Elaine Chew is a senior CNRS researcher in the STMS Lab at IRCAM and Visiting Professor of Engineering at King’s College London. She is principal investigator of the ERC ADG project COSMOS on computational shaping and modeling of musical structures and POC project HEART.FM on tailored music therapy with physiological feedback. Her work has been recognised by PECASE and NSF CAREER awards, and Fellowships at Harvard’s Radcliffe Institute for Advanced Study. She is an alum (Fellow) of the NAS Kavli and NAE Frontiers of Science/Engineering Symposia. She received her PhD and SM degrees in Operations Research at MIT and a BAS in Mathematical and Computational Sciences (honours) and Music (distinction) at Stanford. Her research focuses on the mathematical and computational modelling of musical structures in music and electrocardiographic sequences. As a pianist, she integrates her research into concert-conversations that showcase scientific visualisations and lab-grown compositions.
