Watch the In Love With Love Pt. Three online guitar lesson by Jon Herington from Ear IQ: Reactive Improvisation

In this last section of "In Love With Love," we'll again listen and react, find our collections, and concentrate on an effective strategy when the chords are moving quickly and changing key frequently. That strategy will focus on chord tones almost exclusively. Here it will be extremely useful (as in the study of any song you'd like to improvise well on) to find as many possible voicings for the chord progression all over the guitar, and to identify each note in each chord (make a note of what part of the chord each note is, root, third, fifth, seventh, ninth, etc.).
