R&B

 Abbreviated by its initials R&B or Jumping Music is a musical genre derived in its origin from jazz, gospel and blues. The musical term was introduced in the United States in 1949 by Jerry Wexler of Billboard magazine. It replaced the term known as "race records," considered offensive to the post-war world as well as to the Billboard category of "Harlem Hit Parade" in June 1949, and was mainly used to identify the musical genre that would later develop into Rock and Roll. The original R&B, known today as Rhythm and Blues classic, has evolved taking two popular aspects, one known as contemporary Rhythm and Blues and another that has practically no relationship with the subgenre Rhythm and Blues mainstream.
