Watch the Sweet Notes: 4 online guitar lesson by Robbie Calvo from SoloCraft
Take some time to really understand this section as I am using scale shapes of the A minor pentatonic scale that you probably already know and showing you how to identify and outline your chord changes with the notes from within those scale shapes. The notes A, E and G are your sweet notes over the A7 chord and the notes D, A and C are your sweet notes over the D7 chord. Learn the note names in your scale shapes and also in your chords as this will ultimately help you identify your resolutions. Start to learn the notes on your fretboard, too. It will open up a world of new information to you.
