The Mundelein Psalter is the first complete one-volume edition containing the approved English-language texts of the Liturgy of the Hours with psalms that are pointed for the chanting of the Divine Office. The music consists of simple yet beautiful Gregorian-based modes composed for the Psalter. Developed at the University of St. Mary of the Lake/Mundelein Seminary, the Psalter is designed for use by priests, deacons, religious, and laity, making singing the hymns of the Liturgy of the Hours easier for all.
