In previous lessons we’ve explored both major triads and minor triads, which are two of the most commonly used triads. In this lesson we round out the triads of the major scale with a look at diminished triads.
Seventh chords are chords that include the root plus the 3rd, 5th, and 7th intervals above the root. Another way to think about it is a seventh chord is a triad plus a 7th interval.
If you’ve been exposed to at least a bit of guitar theory, you’ve most likely heard of the CAGED system. It’s a system that allows you to visualize the guitar fretboard by using common major chord shapes.
Learning to apply the guitar number system to chord progressions will literally kick down the door to mastering the guitar fretboard.
Playing chord progressions by position is a great way to familiarize yourself with the different chord voicings found all over the neck. It helps open up the fretboard and reduces dependency on only playing open chords and basic barre chord shapes.
