In music making “in company”, the protagonists have to follow the rules of interaction and create the cohesion of “being together”. At the same time, they try to promote personal goals that depend on specific personal treasure troves of experience. These are continuously being modified also as a result of the exchange between individuals. The perspective of the “individuals in company” leads the emphasis of the investigations to the ways in which the acts of performance, interpretation and local discourse give shape to creative processes in multipart music making and to the definition of the individual, collective and collaborative dimensions in this context.Focusing on the “creators” rather than on the “produced object”, the studies included in this volume explore the diversity of the roles, powers, symbolism, meanings and values given to the “polyphony of voices” in secular and religious traditions based on extensive fieldwork experience. The contributors to this volume also consider the UNESCO’s Intangible Cultural Heritage List in this context, as well as the role of local, national and international awards. By understanding “culture as a drug”, whose absorption is realised within interacting cells, culture appears as a cellular network and music as quite an efficient device for its functioning.
