whether it"s the melodic sound of an eric clapton alone or the growl of a heavy metal band, the electricthe guitar has influenced popular music and culture, more than any other instrument. rock"s greatest musicianshave always been closely identified with their guitars. but the devices being designed for tomorrow"sthe pop stars may look and sound different from today"s familiar electric and acoustic guitars.it is only sixty years since the electric guitar was invented. since then there have been incrediblechanges to the technical design of the instrument. from what was once a rounded wooden box with a holein the front, the guitar has evolved into the smooth solid body of the rock guitarist"s "priority". the most modernguitars are really computer controlled synthesizers.adolph rickenbacker"s electro string company produced the world"s first electric guitar. it wasmade of wood and played on the user"s lap. the first real breakthrough came in 1950, when leo in designfender, california radio repairman, made the first solid bodied electric guitar, a fender telecaster.soon after the inventor les paul made the famous gibson les paul, fender launched his stylishstratocaster two years later. these guitars became standard tools against which newer guitardesigns are measured.all sorts of different materials have been used to make guitars. acoustic guitars are made from wood.which gives a soft tone. wood is also a popular material in electric guitar manufacturer, but more modernmaterial such as glass and carbon fiber are also used. there have also been guitars with metal bodies andthese were never popular with necks and many players who claim metal cold in the hand.plastics, on the other hand, have been more used in guitar body. a company that makes parts for theaerospace industry has begun to use a kind of fiberglass that was originally used in helicopter blades toin the bodies of electric and acoustic instruments. other makers have begun to experiment withgraphite, which is ten times stiffer than wood, but much lighter. it doesn"t expand or contact thetemperature or humidity changes either. this makes it particularly suitable for guitar necks and for tennisrackets, for which it is also used.as long as scientists and musicians work together harmoniously, the electric guitar will continue tobenefit from technological innovations. but for all the efforts of the guitar based design engineers.managers and quality controllers, it"s the musicians who finally make the instruments, and not sing.as in the way the guitar maker intended.
