Watch the String Groups online guitar lesson by Pat Martino from The Nature of Guitar
Parental forms expand further when we consider how many strings they can occur on. Of all the string combinations that exist in all different styles, you'll find that certain string groups are more prevalent in different genres.
While I was on the road in the 60's working with Gene Ammons and Sonny Stitt, and Jack McDuff and Don Paterson, I would go out, leave the hotel, and browse different book stores. On one of those days, there was a very thick book of Hexagrams that I pulled out. I opened it up and looked at a random page, and all of a sudden I saw the guitar strings, as there were six lines present. In each of these hexagrams, I saw each of the different combinations of the six strings on the guitar. From that point forward, I began to see the guitar as a hexagram. It just so happens that the book of hexagrams came from China over 6000 years ago, a book called the I Ching, or "the book of changes".
In this lesson, we'll explore the significance of this finding and how it is relevant to how I look at the guitar.
