Prosody is defined as the #rhythm and #melody of speech.
One problem, though: no method to quantify rap microtiming existed yet, so we had to invent one (it uses #MIDI)!
West Coasters used more pitch variation than East Coasters in speech *and* in rap (only Kendrick did something weird; see full article).
You can see/hear examples of this in the video (the more erratic the graphs’ lines, the more pitch variation).
West Coasters rarely use the 4th count of a bar, while East Coasters tend to ‘hit’ every 8th note.
We found evidence of a language-music connection: West/East Coast variation in rap flows follows the same pattern as West/East Coast variation in AAE speech prosody.
In other words: JAY-Z and SNOOP don't flow the same because they don't speak the same.
Check out their stuff too! Really dope work.
You are appreciated!
