  • Where'd it go?

    Someone once posted a link to a site that showed all the

    chords produced by harmonizing the half-whole Diminished scale.

    I've looked here on the LL and can't find it. I've scoured the Net

    and find similar things, but not what was posted here.



    Does anyone recall this? If so, might you be able to direct me to it?



    Thanks.

    This one?

    That's not all the possible chords, of course. Here's another way to look at it:

    Code:

             |  |  |  |  |  |  |  |  |  |  |  |  | 
    X X X X X X X X X
    dim: 1 b3 b5
    dim7: 1 b3 b5 bb7
    min7b5: 1 b3 b5 b7
    min: 1 b3 5
    min6: 1 b3 5 6
    min7: 1 b3 5 b7

    maj: 1 3 5
    6: 1 3 5 6
    7: 1 3 5 b7
    7b9: 1 b2 3 5 b7
    7#9: 1 #2 3 5 b7
    7b5b9: 1 b2 3 b5 b7
    7b5#9: 1 #2 3 b5 b7
    13: 1 3 5 6 b7
    13b9: 1 b2 3 5 6 b7
    13#9: 1 #2 3 5 6 b7
    7#11: 1 3 #4 5 6 b7 *
    13#11: 1 3 #4 5 6 b7 *
    7b9#11: 1 b2 3 #4 5 b7
    7#9#11: 1 #2 3 #4 5 b7
    13b9#11: 1 b2 3 #4 5 6 b7
    13#9#11: 1 #2 3 #4 5 6 b7

    There may be one or two other possibilities.

    Also remember that, because the scale is symmetrical, four of any of these chord types can be found in any one HW dim scale. Eg (as matt warnock shows) you can find C7, Eb7, F#7 and A7 in the C HW dim scale.

    But then there are only 3 HW dim scales .



    However, thinking the other way, it's worth pointing out that most of these chord types are not normally associated with this scale; and it therefore be wrong to use this scale on those chords - either because the chord will have a specific function that the HW dim scale would disrupt, or because the symbols are used to indicate other scales.



    Eg, the two marked * normally indicate lydian dominant, a very different scale.



    The only chord symbols which indicate HW dim exclusively are:

    13b9

    13#9

    7b9#11

    7#9#11

    13b9#11

    13#9#11



    Of those, I've only ever seen 13b9 in practice, and that's very rare.



    The chord symbol normally used to indicate HW dim is:

    7b9

    - although other scales such as phrygian dominant and altered could also fit.



    Otherwise, the chord symbols in the above table normally indicate (or at least imply) the following scales (among other possible ones in some cases):



    dim: locrian

    dim7: WH dim

    min7b5: locrian

    min: aeolian, dorian, phrygian, harmonic minor, melodic minor

    min6: melodic minor

    min7: aeolian, dorian, phrygian

    maj: ionian, mixolydian, lydian

    6: ionian, mixolydian, lydian

    7: mixolydian

    7#9: altered scale, blues scale

    7b5b9: altered scale

    7b5#9: altered scale

    13: mixolydian

    7#11: lydian dominant

    13#11: lydian dominant



    So the idea would be not to apply HW dim scale to these chords, but (in reverse) to use any of these chords as superimposed arpeggios on a chord which normally takes HW dim - i.e., a 7b9 chord, or possibly any V7 chord.
