Rock Music
Rock music is a genre of popular music that fit into as "rock and roll" in the United States in the 1950s, and turned into a range of different styles in the 1960s and later, particularly in the United Kingdom and the United States. It has its roots in 1940s' and 1950s' rock and roll, itself heavily similar by rhythm and blues and country music. Rock music also drew strongly on a number of other genres such as blues and folk, and incorporated influences from jazz, classical and other musical sources. Many electric instruments are included in rock music for most of the instruments that you can hear when you are listening to rock music.
