I have been playing with the Tone.js Javascript library for creating Web Audio apps and the NexusUI library for creating user interfaces. I am going to work on creating an app for music composition using the concepts of Joseph Schillinger and his “Schillinger System of Musical Composition”. To get started, I have created a sample app available at http://andysylvester.com/files/tonejs_experiments/ which plays a set of tones based on a Schillinger resultant. The code for the app is also on Github. Check it out!
