I didn't include chord symbols in the sketch chart, but added a few piano and guitar voicings for reference. The piece follows 32-bar (AABA) form, where A section is in 5/4 time and B section in 4/4 time.
The harmony at bars 1 - 2 and 5 - 6 of letter A implies an A Phrygian mode (A7susb9), whereas bars 3 - 4 and 7 - 8 suggest an A Dorian harmony (Am7). The letter B denotes E Aeolian (Em7) and Bb Lydian (Bb/E) or C Mixolydian (C7/E) modes. Still, I'm not certain about any of this, and therefore need your advise here.
Are the 8th notes in the A section played in swing time? How about the B section? Please share your thoughts.
