Fifths

An interactive circle of fifths you can hear. Tap any of the twelve keys to sound its major chord and light up its dominant and subdominant neighbours; the hub shows the key signature and relative minor, a strip spells the seven scale degrees with the triad marked, and a line explains exactly which single note changes between the keys you moved through. Recent taps build a progression you can play back. All spelling, signatures, and shared-note counts are computed from music theory, not hardcoded.
