Introduction: The pentatonic scale consists of 5 different notes (hence, the
name pentatonic). The major form consists of the 1st, 2nd, 3rd, 5th, and 6th notes
of the full scale (the full scale contains 7 different notes, plus the octave). The
minor form is a "relative" of the major form and consists of the same notes, except
they are arranged in a different order when played 4 frets lower (i.e., in pitch as
opposed to direction) on the fretboard.
