Mixolydian mode progressions

    Hi all

    I was hoping someone can help me with my tenuous grasp on roman numerals and scales/chords and how they fit.

    I am experimenting with the mixolydian scale which is basically playing from G to G over a Cmajor

    Notes being G A B C D E F G

    Now I was looking at progressions but they are all in this kind of notation

    I-VIIb-VIb-V

    so what does it mean? do they mean that if I number the notes above in the scale that the progression is

    G = I E = VIIb (flattened F) Eb=VIb and D= V

    Or should it be the C major scale which would make it

    C = I Bb = VIIb Ab=VIb and G=V note

    The last would make more sense but is this correct?

    Take a look at this site. I found it recently and it's very useful. The user guide goes into a bit of detail about chords, scales and progressions.

    The I is always the chord that relates to the key. So if the Key is C then C = I and G = V because it's the 5th note in the scale of C and is G Mixolydian.

    Hope this clears it up.

    Hi,

    I-VIIb-VIb-V

    I - C
    VIIb - May mean an B Diminished chord in 2nd inversion, B dim/D
    VIb - May mean A Minor chord in in 2nd inversion, Am7/C
    V - G

    If this is the case then all of these chords are diatonic to C Major in one way or another and will "work" with a G Mixolydian chord.
