Liturgy and the Church's Musical Tradition
Liturgy and the Church's Musical Tradition tests your command of the documents and the calendar: which text governs a decision, what the Church means by the "treasure" of sacred music, and which celebration outranks another.
Documents and their weight
Sacrosanctum Concilium (1963) is the constitutional baseline: 112 on the nobility of music joined to the liturgy, 114 on preserving the treasury, 116 on Gregorian chant's pride of place "other things being equal," 117 on polyphony, 120 on the pipe organ. Musicam Sacram (1967) supplies the practical machinery, including the three degrees of sung liturgy (28–31): a Mass is fully sung only when presidential chants, the readings and universal prayer, and the people's processional chants are all sung. The GIRM is the current ritual book; Sing to the Lord (2007) is the U.S. bishops' particular application.
Chant in practice
The Graduale Romanum is the Holy See's book of proper chants; the Graduale Simplex provides simpler chants for smaller parishes. Singing the proper antiphon with a psalm tone is not antiquarianism - it is the first option in the GIRM, and it can be sung in the vernacular with approved tones.
Precedence
The Table of Liturgical Days settles conflicts. First the Easter Triduum; then Christmas, Epiphany, Ascension, Pentecost, the Sundays of Advent, Lent, and Easter, Ash Wednesday, Holy Week, and the Easter octave; then solemnities of the Lord, Our Lady, and the saints in the General Calendar; then proper solemnities such as a parish patronal feast or a dedication anniversary. Sundays of Christmas and Ordinary Time rank below those.
Worked example
A proper solemnity (the parish patron, or a dedication anniversary) falls on a Sunday in Ordinary Time. Because a proper solemnity outranks a Sunday in Ordinary Time, the solemnity is celebrated, the Sunday readings are omitted, and music is planned for the solemnity with its proper preface. Had the same solemnity fallen on a Sunday of Advent, Lent, or Easter, it would transfer to the nearest day not ranked above it.
Traps that cost marks
Attributing GIRM rules to Musicam Sacram; quoting "pride of place" as if chant were mandatory; forgetting that memorials falling on a Sunday are simply omitted; planning Lenten music with an Alleluia.
