Killer Joe bridge

Discussion in 'Music Theory [DB]' started by Miles Hanson, Aug 27, 2003.


  1. 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!

    Em7b5 would be G Melodic Minor, you are correct. Whereas E7alt would be F Melodic Minor.

    If you want to use melodic minor harmony with the half-dim chord, then you're looking at the 6th mode of the melodic minor. So Em7b5 corresponds to G Melodic Minor.

    Another option would be E Locrian.

    Now your A7#9 chord - if you want to interpret that as an alt chord, then yes, Bb Melodic Minor would be appropriate, as the altered scale is the 7th mode of the melodic minor. So, an A7alt chord would go with Bb Melodic Minor.

    On the other hand, since the #5/b13 isn't specified in this case, you could view this as diminished scale harmony. The difference being, you would have a natural 13th (and perfect 5th), whereas with the altered chord you have a #5/b13.

    So you could play an A half-step/whole-step diminished scale over this chord. The difference between that and Bb Melodic Minor (or the 7th mode thereof) is the F#.

    Either scale should work. If the next chord is D Minor, you might favour the altered scale, because it has the F natural, whereas the dim scale has the F#, which is the major 3rd of D - which might not be what you're looking for.

    Or on the other hand, it might be just what you're looking for...

    Bearded Joe works better as a name. Better ring to it. Have him adjust accordingly.
