As I understand it, the Pentatonic scale is a subset of the Chromatic scale. It has five notes, hence its name. The Major scale has seven notes from the Chromatic scale. I don't have a guitar to hand but I am presuming the notes of the Pentatonic scale are also part of the Major scale. If so why do we guitarists limit ourselves to five notes?
If I have this wrong, please point it out to me. Confused but eager to learn something new each day. Thanks.
