They're just 2-5-1 progressions, filled up to 2-3-4-5-1. A few of the chords don't have the bass notes in them.
For a turnaround all you have to do is the same chords you know or those that I posted with one of these interjected at the end (before you go back to the beginning):
Disonant:
EBb \ EbGBb
GbC \ FAC
(bass note could be D, F or G)
or
Straightforward:
DC \ GbCF (grace note on the Bb)
(bass could be DC or A, if you're feeling weird you can do ADb)
or
Disonant:
G (just below the right hand chord) \ AbDG
F \ GbCF
Eb \ EBbEb (melody note Db just after chord)
(bass could be D, G, or A)
It may take you a second to get used to the sound of the last one.
:wink:
As you can see though, they're all pretty simple chords. Nothing fancy (fat), and all except for the middle one doesn't have any bass notes played.
