Rock is a widely popular and vast genre that gathers together a wide range of different styles A genre of popular music that originated as “rock and roll” in the United States in the 1950s, and developed into a range of different styles in the 1960s and later. Compared to pop music, rock places a higher degree of emphasis on musicianship, live performance, and an ideology of authenticity.
Rock in its original form was a song-based type of music that typically used a verse-chorus structure with a backbeat rhythm and the electric guitar at the forefront of the music being heavier and/or faster than its predecessor genres. The structure and sound of rock is based around a prominent electric guitar sound with a bass guitar and drums providing its rhythm (although electric guitars can also sometimes contribute, usually referred to as rhythm guitars in this context). However, rock musicians have experimented with this base structure from the beginning so any two different rock bands may not sound anything alike or even have similar structures. Rock music from its inception has symbolized the counter-culture and served as a vehicle for rebellion and protest, although the proliferation of the genre has diluted this characteristic’s importance as a core aspect.
