Interactive explorers
Five interactive tools built on one idea: show the structure of music theory — the patterns, distances and groupings — and let the names follow. Each explorer isolates one structural insight and makes it visible and audible at the same moment.
The scale pattern machine
The major scale is one rigid pattern that slides. Key signatures are the black keys it is forced to catch.

Intervals are distances
An interval is an elastic band of fixed length. Slide it anywhere — the names change, the sound of the distance does not.

Chords are stacked distances
A triad is two intervals glued together: 4+3 is major, 3+4 is minor. Watch one note slide a semitone and hear the light change.

The circle draws itself
Jump a fifth, gain a sharp. Repeat. The circle of fifths is not a chart someone designed — it is generated, and you can watch.

Time signatures are grouping
Six identical quavers, grouped 2+2+2 or 3+3. The grouping is the only difference — and it is the whole difference.
