The Baroque period of European history was one in which many styles were forumlated. A development in music fundamental to this era, and with far-reaching consequences in later periods of music, was that of the concerto style for mixed groups or choirs of voices and instruments. From this, the instrumental concerto of the Baroque period emerged as an independent form towards the end of the 17th century. This book is an illustrated survey of the growth and development of the concerto from its origins to the present day. Written by a team of international scholars and music critics, it is designed as a reference work for all who wish to understand more about this perenially popular art form and expand their knowledge of the concerto repertoire.
