    Hi everyone.
    Lesson #9 is showing an A5, C5 and D5 chords in example 9-1. Then in example
    9-2 the chords are C5, E5 ( flat) and F5.
    Why are they not following the usual I, IV, V Chord progression?
    Thank you.

    Hello Sammy and welcome to the forum.

    Not all "Blues" will follow the basic 12-bar form.

    I look at it like this:

    ZZ Top's "La Grange" is an example of a song that pretty much repeats the same figure on the I chord for the entire song.

    The "figure" is actually just a riff using the 1-b3-4 of the minor pentatonic scale played as double-stops/power chords.

    (It's actually a variation of what Griff calls the "Reverse John Lee Hooker style variation in A" in his 52 Rhythm Fills And Variations course, Ex 1-12. A variation on a variation!!:whistle:)

    They play the same figure (Ex 9-1) on the I chord, A, for most of the song and then move it up to a different key, C (Fig 9-2), for the solo. It's the same figure, just moved up 3 frets. C becomes a new I chord. Then they bring it back down to A after the solo.


    If you did play this figure through a I, IV, V 12-bar progression in A it would go something like this:

    A5 C5 D5 for the I
    D5 F5 G5 for the IV
    E5 G5 A5 for the V

    This is what the MG's do with the "Green Onions" riff over the I, IV, V changes in F, using yet another different variation on the rhythm.
