Catholic World Report interviews Joseph P. Swain, author of Sacred Treasure: Understanding Catholic Liturgical Music.
At no time in history has the Church had to hand, in print music and recordings, such a wealth of liturgical music of amazing variety and of the highest quality. At no time have such numbers of highly trained church musicians been available to sing and play that music. At no time has there been such a pitch of interest in liturgy and its music on the part of everyday, churchgoing Catholics. These are the best of times. At the same time, only a tiny fraction of the liturgical music thought by Catholics and non-Catholics alike to be among the most beautiful ever conceived is ever heard by everyday Catholics at mass.
