HARMio

For this project, the user can play any melody, and it will be harmonized in real-time. Sound is generated using a 4-voice triangular wave synthesizer created within the Web Audio API. For any given note entered, I created a database of possible chords. The chords are indexed by tonal center, and are chosen based on proximity to the last implied tonal center. I use a random log-based probability function, and weight nearby tonal centers to occur more frequently, with more distantly related chords happening occasionally. The colors change along with the implied tonal center.
