Every time the cycle repeats, that low E root is right there to support that downbeat. Notice that it doesn’t have to hit every downbeat of the pattern, but it must hit on that repeated downbeat at the start of the cycle. Funky bass lines emphasize beat one and lay a solid rhythmic foundation. I was thinking about “Clair de Lune” and how strange and complicated the rhythm is. I was humming it to myself and couldn’t figure out where the downbeats were. I have previously used Ableton Live to help me learn a classical piece aurally, so I figured I would do the same thing with this one.
