Here is a nice series of chords that a friend showed me recently. You can play them at a steady tempo, or, if unaccompanied, vary the tempo to suit the circumstance. The basic progression consists of four chords.
Eb for 2 beats - play Eb / G Bb D F
C7#9 for 2 beats - play C / E Bb Eb
Fmi9 for 2 beats - play F / Ab C Eb G
Bb13 for 2 beats - play Bb / Ab D G
This is also referred to as a " 1 6 2 5" turnaround, as the chords are 'built' upon the 1st, 6th, 2nd, then 5th notes of the scale (in this case the Key is Eb, so the Eb scale is Eb, F, G, Ab, Bb, C, D and Eb.
Now, to 'spruce it up' a bit, we can take that second chord (C7#9) and play it as before but for just one beat.
Then on the next beat play a C7b9/E by playing E / E Bb Eb for one beat, then on to the Fmi9 etc. as before.
Another 'spruce up' is to, instead of going directly to the Bb13 after the Fmi9, go to a B9 by playing B / A Db Eb Gb for one beat, then on to the Bb13 as before.
This 'series' of chords can be repeated, or 'looped' as needed, and of course, don't forget to experiment with changing drawbars, leslie speed, etc. for good effect.
A good way to 'resolve', or end the chord-cycle is, after playing the final Bb13, to play an E6/9 by playing E / Ab Db Gb and finally an Eb6/9 by playing Eb / G C F.
Hope this's worthwhile for ya's,
