A scene can mean two things. A scene can be the setting of a story, or (what I think you are referring to) it can be a segment of an Act of a play. A scene separation within a play is usually included in order to allow time for a change in setting during the performance. A chapter is a segment of a book. So, to summarize, a scene is a segment of a play and a chapter is a segment of a book.
Rock and roll is a style of popular music that originated from the U.S in the mid-1950s, and by mid-1960s it had developed to an international style known as rock music, though the latter continued to be, rock and roll or rock 'n' roll or rock & roll. The music is associated with performers like Little Richard, Chuck Berry, Buddy Holly and the early Beatles.
