This is my first time doing this, so they may suck.

But here's what I'm hearing. Each chord is held for 4 beats, with the exception of the last two. The single notes in between serve as filler/passing licks.
C-G-C / G-Bb-C-Eb (Eb is optional)
/ G, Bb
Ab-Eb-Ab / Eb-Ab-C
/ Ab, G
F-C-F / F-Ab-C
/ E, F
G-D-G / G-Bb-D (2 beats)
Ab-Eb-Ab / Ab-C-F (2 beats)
/ Eb, D
C-G-C / G-Bb-C
Or, You can change those last three chords to;
G-D-G / G-Bb-D (2 beats)
Ab-Eb-Ab / Eb-Ab-C (2 beats)
/ E
C-G-C / G-Bb-C
Just my 2 cents. Has a very 'dark' tone. Anyways, hope it helps.
