Looks like this guy has it transcribed for the key of Aminor , I would view the D#(b5 blues note) and the G# (leading tone of harmonic minor) as passing tones. Don't know the piece though so can't offer much help. Now if it was Blue Rondo Ala turk by Dave Brubeck that would be another story, Good luck!
