Rhythm and blues first began to take shape as a recognisable music form in the 1940s following the Great Migration, as there was an influx of Black Americans in major cities such as New York, Chicago, LA, and Detroit. This increased cultural diversity brought with it Black American tradition, including blues and church music. The term rhythm and blues was coined by Jerry Wexler in 1947 to categorise a new, polished blues sound being headed by Louis Jordan and his band, the Tympany Five. By the beginning of the 1950s, rhythm and blues was mainly reaching a black audience; existing primarily in clubs and honky-tonks, it was seen as a simpler alternative to jazz. However, artists such as Johnny Otis saw hits with songs such as Double Crossing Blues and Cupid’s Boogie which helped the genre gain a wider, more diverse audience.
