    SW, I hate to keep asking things of you, but would you mind writing out all of the modes (and other "scales" as you see fit) with key neutrality? Like how you did for a few of them as 1, 2, b3, 4, etc. For me that would be a HUGE help to both visualize and apply these different things, without just running different fretboard patterns over chords (which isn't getting me anywhere in terms of knowing what notes to hit to express what I want to express).

    Sure thing.

    The diatonic modes:


    Lydian - 1 2 3 #4 5 6 7
    Major - 1 2 3 4 5 6 7
    Mixolydian - 1 2 3 4 5 6 ♭7

    Dorian - 1 2 ♭3 4 5 6 ♭7
    Aeolian - 1 2 ♭3 4 5 ♭6 ♭7
    Phrygian - 1 ♭2 ♭3 4 5 ♭6 ♭7
    Locrian - 1 ♭2 ♭3 4 ♭5 ♭6 ♭7

    Harmonic minor - 1 2 ♭3 4 5 ♭6 7
    Melodic minor - 1 2 ♭3 4 5 6 7

    Major pentatonic - 1 2 3 5 6 (the major scale, minus the notes that create a tritone, 4 & 7)
    Minor pentatonic - 1 ♭3 4 5 ♭7 (the natural minor scale, minus the notes that create a tritone, 2 & ♭6)

    Common modes from the harmonic and melodic minor collections:


    Phrygian dominant - 1 ♭2 3 4 5 ♭6 ♭7
    Lydian dominant (The Acoustic Scale, or lydian-mixolydian) - 1 2 3 #4 5 6 ♭7

    Some symmetrical scales:

    Octatonic scale - 1 ♭2 ♭3 3 #4 5 6 ♭7 (maybe not the best way to look at this scale, but I find that this is how my brain organizes the intervals)
    Whole tone scale - 1 2 3 #4 #5 ♭7 (also something that doesn't fit the mold of our heptatonic tonal system, so the numbers don't have much meaning)

    For those of us who like to pretend that only minor keys exist...

    Aeolian = minor
    Dorian = minor with a sharp 6
    Phrygian = minor with a flat 2
    Locrian = minor with flat 2 and flat 5

    Harmonic minor = minor with a sharp 7
    Melodic minor = minor with a sharp 6 and sharp 7 (typically when ascending)

    Minor pentatonic = minor without the 2 and 6
    Hexatonic = minor without the 6

    Phrygian dominant = Phrygian with major 3rd instead of minor 3rd
    Lydian dominant = not very minor

    Two more...
    Hungarian = minor with sharp 4 and sharp 7 (and very :metal:)
    Altered Dorian = minor with sharp 4 and sharp 6 :)metal: version of Dorian mode)

    Or you can see both of those as...
    Hungarian = Harmonic minor with sharp 4
    Altered Dorian = Dorian with sharp 4
    In both cases, you can abuse the sharp 4 as a diminished 5th.

    You may also want to look at the Altered scale (mode 7 of melodic minor) to use on any altered dominant chord.

    1 b2 #2 3 b5 #5 b7

    Technically you could also write it 1 b2 b3 b4 b5 b6 b7, but it's more relevant to altered chord construction when written the first way. In context of the chords you'd see the b2/#2 as b9/#9


    Also useful is the Locrian Natural 2 scale (melodic minor mode 6) as an alternative to the regular Locrian scale for use on half diminished/minor7b5 chords.

    1 2 b3 4 b5 b6 b7
