ELECTRIC GUITAR by María Gallardo Urbón – 1ºB
The electric guitar is an electrophone instrument, and it belongs to the electromechanical group.
The electromechanical instruments are those played by a mechanical vibration transformed into an electronic vibration. It is a polyphonic instrument because it can play several sounds at the same time. Also, it is a tuned instrument so it can play sounds that are in the musical scale.
Electric guitars have six strings that look like the Spanish guitars, but they have not got a sound box. As a result of this, they have a weak sound, and in order to listening with clarity you have to connect the guitar to an amplifier.
