I was joking with @johncarlosbaez recently about listening to intuitionistic music (instead of classical). Turns out it's real! "In the ... 1970s, a young composer working at the electronic music studio in Stockholm, named at the time Christer Hennix, found that Brouwer’s intuitionist mathematics had a practical yet rigorous philosophical application: for electronic music and the search for elevated experience". https://www.frieze.com/article/room-sound-objects-abstractions-art-catherine-christer-hennix #CatherineChristerHennix #Brouwer #Intuitionism
The Room is Sound, The Objects Abstractions: The Art of Catherine Christer Hennix

With rare performances at Hong Kong’s Empty Gallery, and exhibiting now in Düsseldorf, the polymath has long worked at the thresholds of perception 

@johncarlosbaez I don't think I can find online any of the work that's specifically inspired by Brouwer, but here is some weird classical / electronic / art music from her: https://www.youtube.com/watch?v=eXxobmct4xY

@RanaldClouston - that's great! My wife and I met through Catherine Christer Hennix, since my wife was a poet and I'm a mathematician. I used to argue with Hennix about intuitionism.
