Prototype written out as piano music: the IV – I – iv – i loop in A major for both hands, with chord names and finger numbers. Press play and follow the cursor. The left hand plays leapfrog pulse (root bass · 1 · 2a · 3), and the right hand sings the tune.
Prototype chord chart
The loop once round, bar by bar, in A major. The roman numeral says the chord's place in the key, so the same chart works in any key.

| 2 | A | I | A C# E |
| 3 | Dm | iv | D F A |

What the sheet music shows
The grand staff: the right hand on the treble staff, the left hand on the bass staff, with the chord names above and a finger number on each note (1 is the thumb). It is the accompaniment: leapfrog pulse (root bass · 1 · 2a · 3) in the left hand, with the right hand free for the melody, over the D – A – Dm – Am chords.
Press play and a cursor follows the music. Above it, Colours paints each note in its key’s colour and Note names writes its letter on its head.
