Approaches to “What is This Thing Called Love?”
The 32-bar “Song Form” – 8 bars, repeated, followed by an 8-bar bridge, to an 8-bar repetition very similar to the first 8 bars (so-called AABA form) – has been a popular jazz structure for almost as long as the 12-bar blues. Taken from popular songs of the early-to-mid 20th Century, the AABA 32-bar form is common in jazz and Broadway musicals alike. To improvise over a 32-bar form requires a different set of principles than 12-bar structures. While both forms have connections to the specific kinds of melodies typical of their forms, looking more deeply at the harmonic progressions allows for a wider variety of improvisational approaches.
