My entry for the REPL.it music hackathon. It visualizes the Tonnetz, a mapping of tonal space which plays a crucial part in Neo-Riemannian theory.
Throughout my dealings with music, I’ve been fascinated by its underpinnings. This explores a lesser-known corner of music theory called Neo-Riemannian Theory, an alternative to the traditional Roman Numerals.
Because Neo-Riemannian Theory is lesser-known (and also possibly because it has a scary name), it is seldom taught before graduate degrees. I enjoy visualizing abstract concepts through code (as I have previously done with the Fourier Transform) so I saw this as an opportunity to visualize and explain Neo-Riemannian Theory in a way that any musician can learn and explore.
Constraints encourage new pursuits and this competition was certainly a case of that. The primary constraint was that it had to run on REPL.it which forced me to leave my comfort zone of developing for Apple platforms in Swift and build a web app to have a GUI.
