Left hand: Pop heartbeat
Long, short, long: the heartbeat under a thousand pop songs. Musicians call it root bass · charleston push (1 · 2& · 3) (root bass rhythm), an easy pattern heard in thousands of songs of the library.

Right hand: Pumping chords
A chord on every eighth note, driving the song forward. It moves with the chords, so it fits every bar of the loop.
