As a musical instrument the guitar has a history which goes back nearly three thousand years. Guitars come in two varieties, the first of which is the acoustical guitar having a flat-backed rounded body that narrows in the middle, a long fretted neck, and usually six strings, played by strumming or plucking. The body of an acoustic guitar is hollow and the sound is produced by the reverberations of sound produced when the strings vibrate.
An electric guitar usually has a solid body with a device known as a pickup - a magnet surrounded by wire - which picks up the vibrations of the guitar strings and sends them to an amplifier which is then sent to the speakers where they are converted into sound.
A Guitar tattoo design is a favorite of musicians, with designs of electrical guitars far out-numbering their acoustical brethren. Electric guitars tend to be more popular with rock musicians, acoustic guitars with Country & Western music enthusiasts and classical musicians, and lovers of Folk Music and Flamenco.
