a lesson in 7 type chord tensions.
I show 3 "Boxes":
chords and accompanying scale that could help in playing thru these VERY common Jazz changes. There is some theoretical explanation as to how to use a diminished chord and scale to color a dominant 7 chord with a b9 ... and as to how to use a melodic minor scale to color one in a different way as an ALT.
Am7 - D7alt - Gmaj7 - and E7b9
this cycle can go on as long as you like, and can give you lots of experience in playing over Jazz changes.
