After talking about major chord substitutions, let me talk a bit about dominant 7th substitutions. Initially, I'll talk about substituting dominant 9th and dominant 13th for the 7th (there's a ton of other subs like 7b5, aug 7, some other time for those). So for one measure of D7 as below D7 / / / / try D7 D9 D13 / / / / or start with the D13 and other such combinations. I'll use the following movable chord fingering - C7 in the 1st position, movable to D7 in the 3rd etc. D7 E--x B--3 (index) G----5 (pinky) D---4 (middle) A--x E----5 (ring) D9 (barre lower 3 strings with the ring finger) E----5 B----5 G----5 D---4 (index) A--x E----5 (middle) D13 (barre B and G strings with the ring finger) E------7 (pinky) B----5 G----5 D---4 (index) A--x E----5 (middle) As with movable chords, this can be moved up and down the fretboard. As mentioned in the previous thread on major subs, this alos serves as an intro to jazz guitar. But they can be used almost in any other style e.g. the dom 9th serves as a nice turnaround to the 12 bar blues i.e. in a 12 bar F blues, the 12th measure can be something like d--^ (down, up on 2nd beat) F Db9 C9--- (sustain for beats 3 and 4) / / / / Next minor chord substitutions and then another dominant 7th substitution using a different fingering for dom 7th. In the beginning, this is going to be some work (more frequent chord changes), but once worked out, u can really experiment.
