You Don't Know What Love Is
You Don't Know What Love Is is a 1941 ballad by Gene de Paul and Don Raye. Its 32-bar AABA form stays in F minor, then opens into major keys on the bridge. Miles Davis, Sonny Rollins, Billie Holiday and John Coltrane all recorded it.
Start with Ella Fitzgerald's 1941 vocal, then follow the song through a trumpet quartet, a tenor sax quartet and Billie Holiday's version with an orchestra. Next come a live piano trio, a Coltrane quartet, a guitar and organ trio and a long piano trio performance from 1992.
Rollins is the only horn. Listen to how piano, bass and drums keep the form moving under the tenor sax.

Count the 32 bars of AABA while the track plays, and note where the bridge begins. A smaller version is to tap your foot and name each A and B as it passes.
Each eight-bar A section stays in F minor and opens on Fm7. The chords move between D♭7 and C7♭9, a Gm7♭5 to C7♭9 pair leads toward F minor, and E7, E♭m7 and D7 pass through in bar 6. The bridge opens on B♭m7 to E♭7 and A♭maj7 for four bars, which puts it in A♭ major. Dm7 to G7 and Cmaj7 then give two bars of C major, and D♭7 to C7♭9 lead back to F minor for the last A, which ends on Fm6. These key areas follow the iReal Pro chart and leave out passing chords.
