Example 22. AB/CD/R poetic form and longer vocal phrases in Willie Dixon’s “300 Pounds of Joy,” verse 2; with x- and r-positions confined to half a bar, some pairs combining with only one predication; multiple call and response pairings in each phrase; and acceleration of harmonic rhythm in last phrase, resulting in abbreviation of the form to ten bars (https://www.youtube.com/watch?v=fJ2UadHc_Qg; accessed September 4, 2020))
