Generative.fm
Generative music walks a delicate balance due to human sensitivity to music: the generated result is always linear (because music only operates through time) and must respect harmonization between elements in ways that other art doesn’t have to. A text generator can make nonsense and a visual generator can be clashing, but a music generator can cause pain with the wrong combination of notes.
This site is a collection of generative music pieces by Alex Bainter, with each piece coded as a separate generator. It’s mostly ambient music, more because Alex was influenced by Brian Eno than for any technical reason.
