Plucked string instruments include types which the performer plucks with her fingers, fingernails, or a [[plectrum]] she is holding, such as the [[acoustic guitar]] and other plucked instruments in which the performer presses a [[keyboard]], causing a mechanism to pluck the string or strings. String instruments in which the player hits the string include the [[hammered dulcimer]] and the [[piano]], although with the piano, the performer presses a keyboard, causing a mechanism to strike the string with a felt hammer. With bowed instruments, the player strokes the strings with a horsehair bow (or, with a [[hurdy-gurdy]], operates a mechanical wheel which strokes the strings. <eod>
