Traditional jazz - refers to the Dixieland and Ragtime jazz styles of the early 20th century in contrast to any more modern style. Specifically the term is used to cover a revival of these styles in the mid 20th-century. Dixieland is a name given to the style of jazz performed by early New Orleans Jazz Musicians. The name is a reference to the "Old South". Dixieland which was developed in New Orleans, is one of the earliest styles of Jazz music. The style combined earlier brass band marches, French Quadrilles, ragtime and blues with collective, polyphonic improvisation. While instrumentation and size of bands can be very flexible, the "standard" band consists of a "front line" of trumpet (or cornet), trombone, and clarinet, with a "rhythm section" of at least two of the following instruments: guitar or banjo, string bass or tuba, piano, and drums.
