The accompaniment with every note named, bar by bar: the bar sheet shows each note as a bar on the staff with its letter inside, so you can accompany Purpose without reading music. The left hand plays slow-dance heartbeat (root bass · 1 · 2 · 3 · 4 (12/8)) and the right hand slow-dance chords.
The main tune of Purpose in letter notes
The real notes from a score, both hands, bar by bar. R is the right hand, L the left; C4 is middle C.
Purpose accompaniment in letter notes
The G – D – Em7 – C – G – D – G7 loop with slow-dance heartbeat in the left hand and slow-dance chords in the right. Notes struck together are joined with a plus; C4 is middle C.
How to read the bar sheet
The player above shows the treble staff (right hand) over the bass staff (left hand). Every note is a bar as long as it sounds, at its place on the staff, with its name inside, and the music scrolls past a line that marks now. The chord names run along the top.
Start with the left hand alone at a slow speed, then the right, then both. When the letters feel easy, try the sheet music.
