This chart of Jazz Styles is derived from Joachim Berendt's The Jazz Book. This book is indispensible to any person seeking a comprehensive survey of the history of Jazz. Berendt masterfully covers the evolution of this complex music from several parallel perspectives, helping readers absorb history from more than one direction. This structure also makes the book a pleasure to browse.
I have adapted the map somewhat to include more specifically some genres of music. Please maintain healthy skepticism towards this two-dimensional representation of a thoroughly three-dimensional culture. Some things that are quite important may not be on this map, and some things that are relatively less important may be, merely by whims of geometry.
