Watch the Torch: Overview online guitar lesson by Jon Finn from Improv Target Practice
Here, the chords, scales and Target Notes are shown, described and demonstrated for "Torch Solo Section". What may not be obvious at first glance is the relationship between the pentatonics. Am7 uses the A minor pentatonic, Emaj7 uses the G# minor pentatonic (half-step lower), and Bmaj7 uses A# minor pentatonic (half-step higher). As soon as you realize this, everything in this solo section becomes much easier to manage.
