Watch the Over a Jazz ii-V-I online guitar lesson by Rob Garland from The Guitarist's Pentathlon
In the solo I'm exploring tension and resolution by beginning on the ii chord (Cm7) using Cm pentatonic, creating altered tension over the V chord (F9) with C#m pentatonic and resolving on the I chord (BbMAJ7) with Dm pentatonic. For less tension I suggest remaining on the ii chord Cm pentatonic for 6 beats, moving up to C#m pentatonic for 2 beats on the V chord, then resolving to Dm pentatonic by moving up for the I chord on its downbeat. Moving up to the V chord pentatonic earlier and staying there for a whole bar creates more tension and gives you time to hear the hip altered sound. Experiment with rhythm and adding a swing feel to your lines.
