Watch the Minor 3rd Ascension online guitar lesson by Joe Pinnavaia from Focus On: Fusion

Playing Through Changes with 4 chords. CMin7, A Min7, F# Min7 and Eb Min7. Idea development is more of a challenge here as you have to visualize more of the fretboard and plan ahead of the changes for a smoother development of ideas. Don't worry it gets better with practice plus I will give you some important ideas to focus on.
Again a simplified approach is what I used here. A lot of pentatonic phrases and looking at viewing the fretboard as I developed some lines and tried to change with the key changes as opposed to the keys changing what I want to do. At 2:25 to about 2:39 is a prime example of what I mean by changing the notes and keeping the momentum going.
