Jazz began to "swing" as musicians began to adopt swing eighths, the string bass, high hat cymbals, and a looser, more rhythmic feeling. This change occurred gradually starting in the twenties notably with Louis Armstrong, and continued on into the 40's. A lot of the music that came out of this period was played by bands of ten musicians or more. Because of this the swing era is also often known as the big band era. In this definitive history of Swing music, The Swing Era documents many of the classic recordings of the era: Begin the Beguine by Cole Porter, Bei Mir Bist Du Schon by The Andrews Sisters with Vic Schoen and His Orchestra, Body and Soul by Coleman Hawkins, Cherokee by Charlie Barnet, Daddy From Georgia Way recorded by Bob Chester and his Orchestra, HEY!
