Thinking of jazz minor ii-V-I progressions composed as an etude simply to learn the keys and voicings.
e.g. Dm7b5 - G7alt - CMm7. A common conventional turnaround after the tonic minor chord could be to add biii7-bVI7 which leads nicely back to ii7b5.
After some time, i would like to ascend a key around the circle of fifths clockwise (most prefer anticlockwise).
I'm having a little difficulty finding a similar common conventional modulatory turnaround that would lead me up a key around the circle of fifths i.e. from CMm7 to modulate up to GMm7 (of course via Am7b5 - D7alt).
There's several options I've found, nothing absolute, and some say its a very uncommon progression to make, but what would be the first choice progression to take?
