From the point of view of popular culture, the electric guitar is one of the most important inventions of the 20th century. More than any other instrument, it defines the tone and character of rock and roll. But when the electric guitar first hit the scene in the 1930s, few people saw its potential. It took some time for the instrument to find its place in American music.
Despite the slow start, the electric guitar has finally found its place. It has inspired and defined's completely new types of music. The electric guitar remains the instrument most prominent in rock music, and the most famous instrument ever released in the united States.
The body is the place where the main differences between acoustic and electric guitars are.
Some electric guitars have a hollow or semi-hollow body with the resonating cavity found in an acoustic guitar, but the most popular electric guitars have solid bodies. The sound is produced by magnetic pickups and controlled by several buttons. If you pluck a string on an electric guitar that is not plugged in, the sound is barely audible. Without a soundboard and a hollow body, there is nothing to amplify the vibrations of the strings.
