Tina Turner in 1985

R&B / Pop

The History of Rhythm & Blues, usually referred to as R&B, developed around the time of World War II (1939-1945). Seeking to escape racial oppression, hundreds of thousands of African Americans migrated from the South to cities like Chicago, New York, Detroit and Los Angeles-- a move that is often called "The Great Migration." That's when the southern sounds of blues and gospel were transformed to create a more city-like sound called R&B.

Through the years, R&B came to be known for its vocals and harmonies. Famous R&B singers range from Stevie Wonder and Tina Turner to today's top groups and singers like Destiny's Child and Alicia Keys.

Pop music (short for "popular" music) is considered a lighter version of rock 'n roll because it has a softer beat and emphasizes melodies. Perhaps the most famous pop singer of all time, black or white, is Michael Jackson, also known as the "King of Pop." Jackson's "Thriller" remains the best-selling album ever, with more than 47 million copies sold all over the world since its release in 1982.
