Such a beautiful song. Juicy J is incredible at consistently hitting the listener with bars that fit perfectly in the space provided by the beat. What I mean by this is that, on a bar-by-bar basis, his lines are consistent in length. It’s one of the things that made Lemonade such an awesome track. So I decided to calculate the variance of bar length. Variance is defined as:
a measure of how far a set of numbers are spread out from each other.
The smaller the number, the more consistent the track. Here’s some numbers from random songs:
Notice Juicy J and Gucci, bother hovering around 1.40 in syllable variance, are the lowest by quite a lot. I think this is a trend we’d see over a big sample size. Gucci and Juicy J’s sound is largely characterized by their writing styles. There’s a rhythm built by this repetition and structure that’s very fun to listen to.
50′s number surprised me but it makes sense. Unlike Gucci, 50 operates between a singy-songy voice and a rap voice in his rapping bars. So, while a rapping couplet might be on average about 15 syllables long, he’ll have a few rhyming bars that are 8 to 10 syllables long. He maintains rhythm by switching to a singy song voice.
