George Gershwin wrote the music for “I Got Rhythm” in 1930. Since then, the chords to that tune have been known as “rhythm changes” and thousands of new tunes have been written over them. (After blues, the rhythm changes are the most common chord changes in jazz. And like blues changes, rhythm changes may be be gussied up.) The backbone of the A section is the I-vi-ii-V cadence (in Bb that would be Bb Gm7 Cm7 F7) which crops up in countless pop tunes. As progressions go, it’s a must-know.
