Diatonic Tertian MegaScales over ii-V7-I Changes


Normal scales are made by stacking 2nds.
MegaScales (my term) are made by stacking 3rds.

You play "Mega" Scales virtually the same way
as you would play any scale.

Here are the interlocking/overlapping relationships
between the common tones in the
successive ii-V7-I chords using the megascale concept
(4C = middle C)

6D = Am's 11th

5B = Am's 9th

5G = Am's b7th


5E = Am's 5th ___ D7's 9th

5C = Am's b3rd __ D7's 7th


4A = Am's root __ D7's 5th ____ G's 9th

4F# = Am's 6th __ D7's 3rd ____ G's maj7th


4D = ____________ D7's root ___ G's 5th

3B = ____________ D7's 6th ____ G's 3rd


3G = __________________________ G's root

3E = __________________________ G's 6th



There are some very cool and useful Jazz improvisational possibilities in here.
