Introducing power chords and their role in rock music
Electric rock guitar playing is generally divided into two areas:
Lead guitar usually involves playing single notes, whereas rhythm guitar playing involves the use of chords. Playing chords involves playing more than one note at the same time.
The maximum number of notes that can be found in a guitar chord is six, but also quite commonly in rock music we use power chords which only have two notes. The musically correct name for a power chord is a five (5) chord.
There are seven natural notes and they are called by the letters of the alphabet namely:
A, B, C, D, E, F, G.
