valerie taylor on 14 Jan 11All kinds of stringed instruments - guitars, pianos, violins - have stretched strings which oscillate when plucked or struck. This oscillation generates sound, which can be amplified acoustically by coupling the vibrations to a large sound-board (for a guitar, the top, and in an upright piano, at the back) or electrically by turning the string oscillations into an electrical signal (using a 'pickup') which can be sent to an electronic amplifier / loudspeaker.
