(repeat)
O.K., now let me explain what is going here using part of the 1st progression:
Eb / Gb-Bb-Db-F
F /
Gb /
G /
Here, we start off in the key of Gb with a Gb major 7th (GbM7) chord in the RH and an Eb in the LH. Together, both hands form an Eb minor 9th (Ebm9) chord. So, one could also argue that we are in the key of Eb minor.
Next, we hold that chord and start running the bass a whole step after the Eb. Sort of like the second part of the basic shout pattern used in shouting music:
Ab / Gb-Bb-C-F
Bb /
B /
C /
Here, we are still in the same key as before, but the chord changes. The 3rd note drops 1/2 step. So, now we have a G major 7th w/a flat 5 (GM7 b5) in the RH and an Ab in the LH. When we put both hands together, the chord becomes an *Ab 9th w/added 13th (Ab9 +13) chord.
*
not really sure about the name, so theory experts u can correct me if i'm wrongNext we do the same thing to the bass line as before, skip a whole note after the Ab. This bass pattern continues throughout the entire progression:
C# / E-G#-B-D#
D# /
E /
F /
F# / E-G#-A#-D#
G# /
A /
A# /
Here, the key changes to E or C# minor and u do the same thing as u did in the key before. It just keeps going and going until u right back where u started. Neat huh? The 2nd progression is the same as the first one, it just starts in another key. Hope yall enjoy it, if u got questions just ask me.
