This book will help pastors, music directors, and seminarians understand the introit texts for practical use in today's liturgies. The introit chant is the last of the Mass propers to be researched in detail. Here Tietze presents their history and development through the ages. He has also composed performable congregational settings of the proper parts of the Mass for the liturgical year.
