Aside from the symmetrical and modal scales, there are yet more facets of scale theory. There are scales more unique to the most dominant genres of music – rock and rhythm and blues (including country, southern rock, light rock, acoustic rock, jazz-rock and blues-rock).
Major Pentatonic Scale
The major pentatonic scale is produced by taking the 1st (root), 2nd, 3rd, 5th, and 6th degree of a traditional major scale – these five-degree intervals create Pentatonic Scales. The major pentatonic is simply comprised of the aforementioned 1st, 2nd, 3rd, 5th, and 6th degrees of a traditional major scale.
Minor Pentatonic Scale
Of course, since a major pentatonic exists, the implication is that there is a relative minor to the major. The minor pentatonic scale is yielded just as a traditional natural minor – from the 6th degree of the major pentatonic. The intervals of a minor pentatonic scale are the 1st, 3rd, 4th, 5th, and 7th of the natural minor scale.
