Electric guitars, introduced in the 1930s, rely on an amplifier that can electronically manipulate tone. Early amplified guitars employed a hollow body, but a solid body was found more suitable. Electric guitars have had a continuing profound influence on popular culture. Guitars are recognized as a primary instrument in genres such as blues, bluegrass, country, flamenco, jazz, jota, mariachi, reggae, rock, soul, and many forms of pop.
History
Before the development of the electric guitar and the use of synthetic materials, a guitar was defined as being an instrument having "a long, fretted neck, flat wooden soundboard, ribs, and a flat back, most often with incurved sides". The term is used to refer to a number of related instruments that were developed and used across Europe beginning in the 12th century and, later, in the Americas. These instruments are descended from ones that existed in ancient central Asia and India. For this reason guitars are distantly related to modern instruments from these regions, including the tanbur, the setar, and the sitar. The oldest known iconographic representation of an instrument displaying the essential features of a guitar is a 3,300 year old stone carving of a Hittite bard.
