Watch the Kneejerk: Overview online guitar lesson by Jon Finn from Improv Target Practice

Here, the chords, scales and Target Notes are shown, described and demonstrated for "Kneejerk Solo Section". Take notice that in the first two chords, playing Eb minor Pentatonic (over the Eb minor chord), then playing D# minor Pentatonic (over the B minor chord), you only change one note. D# (Eb) becomes D. The same thing happens over the next two chords. Less obvious if you're thinking about the 7-note scales, more obvious if you're thinking about the Pentatonics.
