Guitar is stringed musical instrument. The guitars can be fretted or fretless. Guitars are used in a wide variety of musical styles, and are also widely known as a solo finger-picking instrument (in classical style or in fingerstyle). They are most recognised in popular culture as the primary instrument in pop, jazz, blues, country, and rock music. The guitar usually has six strings, like the one being played on the left, but guitars with five, seven, eight, ten, twelve, and eighteen strings are also found.
There are also various kinds of guitars: classical guitar with soft nylon-string and a soundhole, folk guitar with steel-string and a soundhole, or electric guitar with magnetic pickups to amplify the strings (pictured). There are variations like the Lap Steel guitar, Dobro, Harp Guitar, Hawaiian guitars, and others.
