ROCK MUSIC
Rock music is a form of popular music with a prominent vocal melody,
accompanied by electric guitar, bass guitar, and drums. Many styles of rock music also use keyboard instruments such as organ, piano, and synthesizers. Other instruments sometimes utilized in rock include saxophone, harmonica, violin, and timpani. Also, less common stringed instruments such as mandolin and sitar are used. Rock music usually has a strong back beat, and often revolves around the guitar, either solid electric, hollow electric, or acoustic.
