The absence of music from the usual publications of Medieval history and history of art of the Middle Ages is understandable, considering the rarity of sources and the difficulty of recreating the real medieval “sound”. And yet, throughout the last decades, an intense activity of historic-musicological research has been carried out internationally by a selected group of specialized scholars. The ambitious goal of this work is to set the Middle Ages music within its historical and cultural context and to provide readers interested in different disciplines − though not musicologists − with an overall picture of music in the Middle Ages; multi-faceted, plain, enjoyable, yet scientifically rigorous. To achieve this goal, many among the most prominent scholars of medieval musicology, at an international level, were involved, along with archaeologists, experts of acoustics and of architecture, historians and philosophers of medieval thought. The exceptional set of images required by the chapters represents an integral part of the text and of the sources available.In addition, there is a developed system of unpublished maps aimed at accompanying the reader in a fascinating journey through a network of places, cultural influences, rituals and themes peculiar to the Middle Ages. The chronological period here covered spans from the origins of the Late Antiquity, through the High Middle Ages up to the end of the XIV century.
