The modern liturgical movement owes a great debt to Solesmes monk Dom
 Eug ne Cardine (1905-1988), whose tireless research in the ancient
 manuscripts uncovered the elusive secrets of Gregorian Rhythm, thus
 revealing some of the original pristine beauty of Gregorian chant. In this
 volume, Dom Cardine sums up the origin, decline, and restoration of the
 chant, and challenges researchers to continue his work.
