Watch the SECTION 2: Diatonic Harmony online guitar lesson by Erich Andreas from Nashville Number System Decoded

In this section, you're going to learn about diatonic harmony, how chords and chord progressions fit together, the three basic chord triads (major, minor, and diminished), and how they apply to the NNS. Finally, I'm going to show you chordal scales for the keys of C and G. These tools are going to dramatically increase your skill set when approaching the NNS.
