With a beginning in the early 20th century in African American communities of the U.S. South, Jazz brought together music from both Africa and Europe. The word “jazz” itself was first used to reference music in Chicago about 1915. From its beginning, Jazz incorporated regional styles such as New Orleans’ Dixieland, the big bands of pre-World War II, and Latin Jazz. Because of its variations, which now include international, jazz is very hard to define.
