In 1996, he withdrew from Amherst College and spent a year living in Mortlake, near London, studying composition privately with Michael Finnissy.
This process, which he developed in 2009 with the Swiss musicologist Olivier Senn, is based on millisecond-level microtemporal analyses of recorded performances.
The six works in the series The Artist and his Model (2010–2012) are based on Alfred Cortot's July 1931 recording of Debussy's Prélude, "...La file aux cheveux de lin".
Other source works have included Maurizio Pollini performing Anton Webern (nach Webern, nach Pollini 2011), Thelonious Monk improvising on "Body and Soul" (Now anything can hang at any angle 2011), and Pablo Casals performing Johann Sebastian Bach (Ebenbild 2014).
Writings on these works, by Beaudoin and others, have appeared in the Journal of Music Theory, Perspectives of New Music, Divergence Press, The Journal of Aesthetics and Art Criticism, and David Bard-Schwarz's 2014 book, An Introduction to Electronic Art Through the Teaching of Jacques Lacan: Strangest Thing.
