The singular character of this collective volume consists in the fact that it brings together articles dealing with liturgical music in almost all the autocephalous Orthodox Churches. By gathering numerous studies on music in Orthodoxy within a single and accessible volume, this collective endeavour serves as a testimony to Orthodoxy’s ability to unite its many voices in a single harmonious chant. Music unites and brings people together. Offering an in-depth overview of the diversity, beauty and creativity of Orthodox liturgical chanting, this book testifies to the importance and vitality of this field of study and contributes to its continued enrichment, while promoting collaboration and the exchange of ideas within the Orthodox academic and musical communities. Readers will discern through this volume the inherent universality of Orthodoxy and, notably, recognize that music extends an invitation to dialogue, even amidst differences in language, cultural specifi cities, and historical trajectories. Readers will also gain signifi cant insights into the history of each Orthodox Church over the last two centuries, and the concerted efforts required to adapt the human expression of the Christian faith to the specifi cities and musicality of each language.His Eminence Joseph, Metropolitan of the Romanian Orthodox Metropolis of Western and Southern Europe Edited by Ciprian Costin Apintiliesei and Emanuel Dobre, professors at the Orthodox Centre for Studies and Research “Dumitru Staniloae” in Paris, this collective volume brings together 28 articles written by 27 renowned professors, researchers and specialists in the fi eld of Orthodox liturgical music.
