Birthday written out as piano music: the IV – ii7 – IV – ii – I loop in C major for both hands, with chord names and finger numbers. Press play and follow the cursor. The left hand plays heartbeat octaves (rocking octaves) and the right hand freeze-tag chords.
Birthday chord chart
The loop once round, bar by bar, in C major. The roman numeral says the chord's place in the key, so the same chart works in any key.

|---|---|---|---|
| 1 | F | IV | F A C |
| 2 | Dm7 | ii7 | D F A C |
| 3 | F | IV | F A C |

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: heartbeat octaves (rocking octaves) in the left hand and freeze-tag chords in the right, over the F – Dm7 – F – Dm – C 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.
To see the real melody written out, play “The part you know”: the sheet music changes to it.
