The Origin and Development of The Guitar parallels that of Man on Planet Earth himself. The Guitar is ancient in it's history, and it's tuning is unique... having it's origin somewhere around 50,000 years ago, and most likely far beyond that date going back perhaps to almost the Dawn Of Humankind. Instruments other than guitars, made from bone or other long lasting materials have been discovered worldwide with the same specific frequency relationship of the notes E,A,D,G,B,E... that still are used for tuning the guitar today.
