"Afternoon in Paris" is a 1949 jazz standard. It was written by John Lewis. "Afternoon in Paris" has a 32-bar AABA form and is usually played in the key of C major. In several of the song's phrases, the tonal center changes (when played in C, there is a shift to B♭ and A♭), defining a complex harmonic structure that is of interest to both theoreticians and soloists.
