Post WW II Big Bands

As big bands developed out of Swing Era after WW II, they used many different elements to color the music – Bebop, Cool Jazz, Hard Bop and Post Bop – just to name the Bop family. Similar to the transition from Swing to Bebop, rhythm sectons became looser, harmonies more sophisicated and there was generally a larger palette for the composer or arranger. So, we have made this category its own genre rather than tie it any one genre or era.
