This volume covers the period from the Vigil of Pentecost through the 17th Sunday after Pentecost. Thematic material for each piece is taken from one of the Propers of the Mass (Introit, Gradual, Alleluia, Offertory, Communion), and the entire collection is keyed to the three-year lectionary shared by Roman Catholics, Episcopalians and Lutherans as well as some denominational bodies not strictly liturgical by nature. The pieces range in length from roughly one to three minutes (approximate times are found at the end of each number) and the level of difficulty ranges from easy to moderate. The chant melodies themselves are necessarily taken from the Roman Gradual.
