Drawing upon Scripture, Magisterial teaching and his vast experience as a conductor, organist, composer and liturgical director, Aurelio Porfiri has created a compact but comprehensive handbook for liturgical music directors. His experience as a conductor and his intimate knowledge of the inner dynamics of choirs form the foundation for guidelines that are very practical and, at the same time, quite beautiful in their reverence for proper liturgical music. The book progresses in a logical manner, beginning with a look at the ancient practices to be found in Temple worship and the central place of King David as a role model. Porfiri then proceeds to offer insightful reflections and useful advice on topics such as the proper formation of singers, conductors and clerics; guidelines for musical selection based upon his deep understanding of the Catholic Mass; various strategies for recruiting, training and forming singers - including the importance of cultivating a love for sacred music in children. The writing is clear, warm, and straightforward and is informed by his substantial knowledge of Church teaching on sacred music from Pius X's Tra le sollecitudini through what was actually taught at Vatican II in Sacrosanctum Concilium. This is a book that can serve liturgical music directors in many different Parish contexts. Its emphasis on deep listening and creating a healthy, spiritually nourishing environment for liturgical singers will be of value both to beginners and more experienced conductors.
