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.

If you are struggling with playing chords past the fourth fret in the key of C major, this post is an essential first step in unlocking the guitar fretboard. Third intervals are in every major and minor chord, so becoming familiar with these will help you understand chord structures. These exercises are also great warmups.

When you hear the term “intervals” do you think of guitar chords and harmony or lead lines and solos? Either way, intervals are the foundation of both! Although they may seem boring or unimportant, understanding the different intervals are and how notes relate to each other will help you improve your rhythm and lead guitar skills.
