In the discussions and debates surrounding liturgical music of the past fifty years, music theorists, critics, and historians have contributed little, and their counsel has rarely been sought. Whenever the matter of liturgical music arises, most often in parishes, but sometimes in episcopal conferences or in the academy or in Vatican documents, the nature of the music, as music, almost never affects the discussion.With Sacred Treasure, Joseph Swain, a distinguished musicologist and accomplished performer, attempts to change that. He offers a theory for building authentic traditions of liturgical music for Roman Catholic parishes. This book is an exercise in pragmatic music criticism. By providing a rational basis for evaluating the essential issues, Swain seeks to show how a spiritually wholesome stability might supplant the confusion.Sacred Treasure shows how the hard facts of music must be taken into account in any holistic conception and any lasting form of liturgical music.
