Modern Blues Soloing #2

[JacobWood]

Can someone help me with lick 4 on solo 2?

Griff explains the GMaj7 arpeggio as the four chord of the A five chord, which would be E. But G is the four chord of the A four-chord (D).

Thanks!

Griff discusses this in the section "Borrowed Arpeggios" back on page 20 in the manual and in the Section 4 video.


G Maj7 is the IV chord in the Key in which A7 is the V chord, i.e. D Major.


The A7 chord is the V chord in the Key of D.

The IV chord in the Key of D is G Maj7.

You are playing the G Maj7 arpeggio over the A7.

You "borrowed" it from the Key of D; the same Key A7 is actually in.


Also:

A7 = A C# E G (1 3 5 b7)

G Maj7 = G B D F# (in A, these are the b7, 9, 11 & 13)

By playing the G Maj 7 arpeggio over the A7 chord you are adding the 9, 11 & 13 sounds to the A7 chord.

Combined, they are all notes of the A Mixolydian scale : A B C# D E F# G

You're just "seeing" and playing notes of the A Mixolydian scale in a different way, a G Maj7 arpeggio over an A7 chord.

If you stack them all in 3rds you have an A13 chord: A C# E G B D F#

Thanks for the explanation!
That's what I gathered but I was confused because Griff says the four chord of an A five chord is G (about the 14:40 mark)

 

[Paleo]

Griff says the four chord of an A five chord is G

It's just quicker than saying "If A is a V chord you are in the Key of D and the IV chord in the Key of D is G".

Gotcha! I get it now, I just had to make my mind jump through one more hoop.

Thanks!
