The title to this lesson is scary. Major scale harmony is the key to learning, writing and playing great songs. By harmonizing each note of the major scale with a triad, we can learn all the chords available to us in any major key. This is how every song is played. There will be no mystery to what major or minor chords are available to you when a session leader calls out a key.

Learn this pattern and shift it into all keys all over the neck. Learning these chord numbers are the first step in learning the infamous Nashville Number System. We'll use this in everything we learn in the rest of this course. Be careful, you may learn some music theory along the way!
