Bas during his PhD defense

Research

Why do humans make music, and how do they do it? Why are we a musical species? These are the questions that motivate my research. I use computational methods to study how musical traditions differ. Mapping the diversity of musics across the globe, is a key step in understanding the cultural evolution of musics.

Doctoral dissertation

Cover

On Friday 23 February 2024, I defended my doctoral dissertation Measuring musics: Notes on modes, motifs, and melodies. The dissertation consists of several studies that try to measure properties of musical traditions. In the same way linguists have compared languages to work out how they are related, what properties are common, and which are rare, musicologists have compared musical traditions or musics. To do so, you somehow need to measure the properties you are interested in. My dissertation develops computational methods to measure musics. It discusses, amongst others, modes in plainchant, inventories of rhythmic and melodic motifs, and shapes of melodies.

Academic biography

My academic life has been closely connected to the University of Amsterdam, where I did my bachelors (Bèta-gamma) and masters (Logic), both with a major in mathematics. I then went on to do a PhD in computational musicology with Jelle Zuidema, John Ashley Burgoyne and Henkjan Honing at the Institute for Logic, Language and Computation, which I defended in early 2024. Currently, I am a lecturer in cognition and computation at the department of musicology at the Univeristy of Amsterdam, while still affiliated to the Music Cognition Group.
