More geometry in music: the 'cube dance'. This shows all the chords called major, minor and augmented triads. Two of these chords are connected by an edge if they differ by just one note. We get 4 cubes connected at their corners! Augmented triads are choke points: if you want to get from one cube to another, you have to go through an augmented triad. (1/n)
