This book explores a fascinating and often overlooked chapter in musical history and delves into the intriguing possibility that the classical repertoire for wind ensembles – particularly Harmoniemusik – and French Baroque performance traditions may have influenced the development of popular music in colonial America and the evolution of New Orleans jazz. Could early European military musicians and music educators have been the unseen architects of jazz, laying the foundation for its emergence? This book offers a compelling exploration of this question, uncovering forgotten aspects of the genre's origins and shedding new light on the role of military and classical wind music in shaping the sounds of a new era.
