My mini course on "Power Chords" is an entry level course introducing you to these awesome but powerful musical devices.

Power chords are typically made up of just 2 notes which strangely makes them sound "bigger" than more complex chords. The "Power" part can really come into play when using distortion on your amp or with a pedal. Also, power chords make up not only the foundation of rock music, but the blues as well, so It's extremely important for you to be able to play and understand them.
