Ben Brown, guitar player for psych-punk-pop garage faves The Cuts, is posting a series of guitar lessons at the Birdman Records Web site. The first tutorial is on the joys of overtones:
Why is this relevant? Well when you play with distortion as you should most of the time the overtones are drastically more apparent. That is one reason why power chords sound so good. The combination of root and fifth and there respective overtones are synchronous and reinforce each other thus creating the "power" behind the chord.
