Actually, first the disclaimer. As teaching is a form of
passing of information, here's where mine is coming from: The
ideas behind subs and the scales to go with it, are originated from my studying Grove's, Mock's, and Gambale's approach to that subject. Here we ho, we'll start with the three main forms in major and then the
remaining 6 in minor. And then plurality.
Tonights guest is the the the I Major chord.
To sub for the major (with the same function) use any of
the diatonic
or altered forms listed. The scales are to play through the
chord, but
add chromatic passingtones by taste.
For the sake of argument we're using C as key.
I suggest the major scale, one can use the
major pentatonic
(nothing than a major scale minus the fourth and
seventh)
Diatonic Forms
Chord----spelling----scale choice / Number positions on Maj scale
Cmajor---c,e,g-------C major, C lydian (4th mode Gmajor) 1-3-5
C6------- c.e.g.a-----C maj, C lyd 1-3-5-6
Cmaj7----c,e,g,b-----C maj, C lyd 1-3-5-7
Cmaj9----c,e,g,b,d---C maj, C lyd 1-3-5-7-9
C69------c,e,g,a,d--C maj, C lyd 1-3-5-6-9
Cmaj9#11--c,e,g,b,d,f#---C lydian 1-3-5-7-9-11...half step up
C69#11----c,e,g,a,d,f#---C lydian 1-3-5-6-9-11....half step up
Cmaj13#11-c,e,g,b,d,f#,a---C lydian 1-3-5-7-9-11..half step up-13
Altered Forms
Csus4------c,f,g---C major
C6b5-------c,e,gb,a--C lydian
Cmaj7b5---c,e,g#,b---A harmonic minor
Cmaj9b5---c,e,gb,b,d---C lydian
Cmaj9#5---c,e,g#,b,d---A harmonic minor
C69b5------c,e,gba,d---C lydian
Cmaj9#11#5--c,e,g#,b,d,f#---A melodic minor
Cmaj13#11#5--c,e,g#,d,d,f#,a--A melodic minor
Obviously the lydian stuff
would be for subs on the IV chord (not in blues though!!)
Any questions/comments? Let me know.
