    Default Chord notation questions re + - and o

    I found this chart online with + and - on some chords and want to check and make sure I am interpreting correctly.

    A-7 = Aminor7
    E- = Eminor
    B+ = B Aug (triad with sharp 5th)
    E-6 = E minor 6 (never heard of it, would be a minor chord with added 6th?)

    There is also G and a triangle with I know is Gmajor7.

    Then there is G#dim, C#o, and F#o with a line through the circle. I'm not sure how they differ. I know dim and dim7 chords and think the little o is one of those but I don't know why it would include all three and what difference there is for the o with a slash.

    This is the chart -- https://musescore.com/user/355131/scores/5179469

    My guess on "o" is it is dim7 and "dim" is dim triad with no 7th. But I done know what the slash o is.

    I found this key https://musescore.org/en/handbook/chord-symbols
    That clears up the o slash. I guess the only doubts are why both dim and "o" are used. And I ain't never seen a -6 before.

    Slash o is half diminished AKA min7b5. root, b3, b5 and b7. Full diminished is root, b3, b5 and bb7 (double flat 7th)

    No mandolin players listed on page 7.

    Darol Anger is listed under violin and there's a single cello player, David Baker.

    In a theory class there's a distinction between the diminished triad (g#-b-d) and the diminished seventh chord (g#-b-d-f). But in my long experience I've never seen a pop or jazz arranger actually use the triad. So it's pretty common to see "dim", "dim7", "o", and "o7" all referring to the four-note chord.

    E-6 = E minor 6 (never heard of it, would be a minor chord with added 6th?)
    It's a funny one isn't it? The 6th scale degree of the harmonic minor and the aeolian mode / natural minor are flattened while in the melodic minor and dorian mode the 6th is natural - or unflattened. The minor 6th chord is used in Blue Bossa - C minor 6th and is associated with C dorian - ie with the unflattened 6th scale degree. But I'm not sure if that is what is always implied by minor 6th.

    These links are handy for various shapes. Some good minor 6s here.
    1-b3-5-6. So E-6 would be E-G-B-C#. If you decide to drop a note drop the B.

    Thanks for the responses. Turns out this wikipedia article covers most of it (except the "-") https://en.wikipedia.org/wiki/Chord_...popular_music)

    I'm not going to worry about the diff between dim, o, dim7, and o7 and assume I can do whatever fits. I get the o slash (half-diminished now.

    Eř7 = Em7b5 (half-diminished)

    the slash (Eř7) notation tends to be used in classical. Jazzers will use m7b5

    Cm6 = C Eb G A = C minor triad with a major 6th change the root to A (A C Eb G) and its Am7b5 (or Ař7)
