The Power of Pentatonics
From the site:
Pentatonic scales are everywhere! They can be found in folk music from all around the world including: China, Japan, Greece, Poland, Indonesia, Ethiopia, and Scotland. American spirituals such as “Amazing Grace” and “Old Man River” utilize pentatonic scales exclusively and many rock guitar players have built their entire careers upon the five notes of the minor pentatonic scale alone. Pentatonic scales can be found throughout the music of Impressionist composers such as Maurice Ravel and Claude Debussy as well as in the music of modern jazz giants like John Coltrane, Herbie Hancock, and Chick Corea.
