The Electric guitar's popularity began to increase during the Big Band era of the '30s and 40s. Due to the loudness of the brass sections in jazz orchestras, it was necessary to have guitars that could be heard above the sections. Electric guitars, with the ability to be plugged into amplifiers, filled this void.
It is believed that the history of the guitar began in the ancient Near East. There, the archeologists found instruments and representations of them that served as landmarks or guideposts in the relatively uncharted territory of the guitar's beginning.
It's important to have a structure to your practice sessions to make any progress on the guitar, you may have found yourself sitting down for an hour noodling and find your progressing but with a little structure you'll be able to progress 200% more than before.
