In my bar piano arrangement of the song "Georgia On My Mind" (pub. Schott), in the first measure, half beat, there is an interval of a diminished octave in the left hand: G# and G surrounding D. The chord symbol over that harmony is E7#9 in the sheet, but then, the arranger does not use Fx but G.
What scale, beside the chromatic of course, could include E7#9? Is there any known in western music? Minor scales offer certain degrees of freedom concerning the 6th and the 7th degrees, but as far as I know that does not mean I can use both 6ths at once.
Some context to outline why I think I need it: In a nutshell, I would use the chromatic scale as the last escape only, because I would have to let go off any error checking for the regions covered.
It is sometimes a struggle for me to integrate these tension notes into my ideal mindset of diatonic scales plus not so-diatonic-minor scales. Especially when the tension notes are put in addition to non-alterated tones in the stem octave. This mindset would have its benefits in context of programing at least, so I hope I could stick to it. So I rather tend to see that harmony as a varied Bm. Precisely, let it be harmony E7#9 regarded as compliant to scale B minor.
Until now, code stumbled upon that somewhere in my DIY computer program that I also use to double-check that I read notes correctly, which is achieved by observing that covered notes viewed horizontally comply to a scale vertically covering that (part of) measure. Think of light polarization, this works likewise. The scale to check notes against I indicate by a two- or three-letter abbreviation. This abbreviation is looked up in a mapping of scales. I could add another to my collection of diatonic and minor-variant scales, one of the latter type: >2>1>2>2>1>1>2>1 semitones, observe there are 9 steps, 6 and #6, so 9 steps in total. But light-heartedly inventing arbitrary non-diatonic scales has not much in common with learning and practicing music theory.
My idea is "dm" (among mn = [natural] minor / aeolic with b6/b7 compared to major, hm = harmonic minor with b6/j7, mm with j6/j7), spoken "dissonant minor". But I would rather prefer some established term if there is one.
