Harmonic sequencers by Luisa Pereira

Luisa Pereira knows about music, interaction design and sequencers. She has developed a few good looking, easy to use harmonic sequencers. Classic western harmonic theory and the rules of counterpoint in two handy wooden boxes. Should be on the market!

This chord-maker is based on The Geometry of musical chords by Dmitri Tymoczko, published in Science in 2006.
