This is where guitar starts to get fun. Using the same chord progression and the same pentatonic minor scale, we can add 2 more notes and create a whole different sound. The minor scale. The red notes are still G, the gray notes are the ones from the pentatonic minor scale that we have been playing with. The purple notes are the new ones. A and Eb (can also be called D#). So go back to the chord progression I posted before and try playing this scale over it. Practice until you figure out how to make it sound good. Its not at easy as the previous scales, but you will get used to which notes sound good where.
