THE PROFESSOR In this fun and cool-sounding lesson by Sinisa, you can see a fairly straight-forward Celtic chord progression, that would also sound at home in a folk, rock, or country tune as well. While you may have already mastered these chords on the guitar, and played them many times over different songs that you know, you should also be able to understand why these chords sound and work the way they do in tunes such as this one. 

Learning how to build major triads and build minor triads can come in handy when playing chord progressions such as the one from this lesson. Getting these shapes in your ears, under your fingers and grasping the theory behind their constructions, will come together to give you a full understanding of the chords you’re strumming in your favorite songs and progressions.
