In the practice room at school today, my piano player friend (known from here on as Bearded John) and I were practicing Killer Joe. I was attempting to play from memory, but the bridge is were I stumbled so we stopped so I could analyze my mistakes and come up with a better line. Bearded John told me one of the options I have on the first measure of the bridge, which is E half-diminished, is F melodic minor. I disagreed and said G melodic minor. My reasoning for this being that the next chord in the bridge, A7#9, could be reckoned from Bb melodic minor, correct? It's a minor ii-V. We aren't fighting over it, but I don't have my first lesson of the semester until next week and I would appreciate some knowledge to trickle down from yee jazz theory gods on high. Thanks in advance!
