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: slow-dance heartbeat (root bass · 1 · 2 · 3 · 4 (12/8)) in the left hand and slow-dance chords in the right, over the G – D – Em7 – C – G – D – G7 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.
