Below are five reharmonizations of Here's That Rainy Day, beginning with my version; then the standard lead sheet; and then four other versions, each becoming gradually more complex than its predecessor. The last four versions are analyzed with Roman Numerals for syntax and function within each progression. These are not offered as paradigms of musical art, but rather as an introduction to various standard harmonic styles. After studying these, go back and analyze my version at the beginning yourself, should you be so motivated.
Thanks so much for posting this, Ed. Did you record this? (If not, would you recommend a particular recording or two for listening - Bill Evans, Dave Brubeck, Oscar Peterson, Freddie Hubbard, Chet Baker ?)
