A cappella Publisher Desc.  This choral song cycle consists of settings of the four main Marian antiphons used in the traditional Latin liturgy: Ave, Regina coelorum; Regina Coeli; Alma Redemptoris Mater; and Salve Regina. The music makes use of much expressive dissonance but within the limits of a purely diatonic collection of pitches. The antiphons are presented here in the order in which they would be sung during the church year. If performed as a group in a concert setting they may be sung in this order or the order may be changed for musical reasons. They may also be performed individually for liturgical or concert use.
