Pentatonic is a favorite among guitarists because the finger positions are easy. It's very common in blues, rock, metal and their many sub-genres. Rock often times drops the 3rd in a chord and only plays the 5th and an octave {aka power chord} The third of a chord is sometimes referred to as the color tone because it determiners if the chord is major or minor. The power chord is also a favorite in these genres because of it easy finger positions and because it fits within the pentatonic scale.
