THE PROFESSOR As you can hear in this very cool lesson by Piotr, there is a lot you can do as far as creating interesting chord progressions using triads in inversion and m7 chords, both of which might sound a little advanced, but are not as hard as you think to get under your fingers and into your theory vocabulary. 

Learning how to build and use minor 7th chords for guitar as well as triad inversions for guitar can go a long way in expanding your theory knowledge, helping you break out of the standard chord shapes on the neck, and let you dig into a Funky chord style like Eric Clapton all at the same time.
