Via robot wisdom, composer Dmitri Tymoczko has written visualization software that makes sense of the harmonic movement of a piece of music.
“Tools like these have helped people understand music with both their ears and their eyes for generations,” Tymoczko said. “But music has expanded a great deal in the past hundred years. We are interested in a much broader range of harmonies and melodies than previous composers were. With all these new musical developments, I thought it would be useful to search for a framework that could help us understand music regardless of style.”
The homepage for ChordGeometries 1.1 includes a link to the published paper and three some short animations to accompany a fragment of a Chopin piano prelude. I’d love to see what a Billy Strayhorn piece like “Lush Life” looks like.
