Chord tonality is a technical term for identifying if a chord is major, minor, augmented, or diminished. When we play chords in a major key, it would help to know if we’re playing the right tonality. Play an A minor chord when you should be playing an A major chord and you’ll know exactly why this is important.

In this lesson we will break out of playing chords in open position (the first 4 frets) and discover triads (the 3 main notes that define a chord) and full chords across the guitar fretboard. Then we will look at how major chords are built using a major third interval and a minor third interval.
