Hey there- So i was listening to "Lights" by Ellie Goulding (https://www.youtube.com/watch?v=0NKUpo_xKyQ), every once in a while I like to try and improvise to random songs that seem to be popular. The bass rhythm to this song does not seem to be standard, and it's confusing me. As far as I can tell, the bass line plays 7 eighth notes on the first chord, 9 on the second, 7 on the third, and 9 on the fourth. Is this correct? If so, why? I've never really seen this before, and I'm sure its a super easy answer. It's just one of those things that sounds so simple but I can't figure it out! Any help would be appreciated !
