Proceedings of the International Conference on New Interfaces for Musical Expression

The Scale Navigator is a graphical interface implementation of Dmitri Tymoczko’s scale network designed to help generate algorithmic harmony and harmonically synchronize performers in a laptop or electro-acoustic orchestra. The user manipulates the Scale Navigator to direct harmony on a chord-to-chord level and on a scale-to-scale level. In a live performance setting, the interface broadcasts control data, MIDI, and real-time notation to an ensemble of live electronic performers, sight-reading improvisers, and musical generative algorithms.
