Watch the ii V Around The Tree online guitar lesson by Fareed Haque from 30 Beginner Jazz Licks You MUST Know
Guide tones for a ii V-I are really cool: In the key of C, a ii-V-I is Dm7-G7-Cmaj7, right? So, the guide tones are F and C for Dm7, F and B for G7, and finally E and B for Cmaj7. Play these again on the D and G strings. Notice that the notes move smoothly downwards, one note staying the same and one note moving down a fret. And, these are all the notes you'll need to comp with! Add a 9th or 13th, or even just the 5th on top to fill out the chords if you want, but these 2-note chords are perfectly fine and professional jazz comping voicings. Don't over complicate things - keep it simple and focus on your rhythm and swing!
Let's look at the guide tones here for this ii-V-I lick. Notice that the lick also follows the movement of the guide tones: We start on an F, The 3rd of our ii chord Dm7, then we circle down to the root and back up the Dm7 arpeggio to the 7th of Dm (C), and then down to B, the 3rd of our V chord, right on the beat, wiggle around some, and then circle around E, the 3rd of Cmaj7, landing again right on beat 1!
So, as you're hopefully starting to see, these licks outline the movement of the guide tones in a very literal and almost mechanical way. Just so long as the lines follow the movement of the guide tones you can be very creative and still come up with lines that will work.
