When we say "Time After Time", most people will immediately think of the big Cyndi Lauper hit. After all, even Miles covered that tune, and it is a good one.
But 6 years before Lauper was even born, Sammy Cahn and Jule Styne collaborated to create a great ballad by the same name. They wrote it for Frank Sinatra, but it has been covered by musicians from Chet Baker to Rod Stewart. Although it isn't played as much as some tunes in the America Songbook, it is well worth learning.
It is a familiar ABAB form in 32 bars. The chords aren't too treacherous, with the A section working the familiar soda pop progression of I-vi-ii-V. This arrangement has some harmonic substitutions to give it more interest as a jazz ballad.
