These are descriptions for two sacred music courses that would be offered at an independent seminary with both men in formation for priesthood or permanent diaconate as well as lay men and women studying for parish work:

Music in the Liturgy: a Study of the Documents

This course will survey the documents governing the use of music in the liturgy, beginning with Pius XII’s motu proprio Tra le sollecitudini (1903) through the USCCB’s most recent guidelines, Sing to the Lord: Music in Divine Worship (2008). Perspectives on pre- and post-conciliar approaches and the “Mind of the Church” will be considered, and application of these principles to sacred music programs in parish churches today will be explored.

A Survey History of Western Liturgical Music

This course will trace the history of music from pre-Gregorian chant through the present, with a focus on the influences of Western art music on the music of the liturgies of the Roman rite. This course is intended to be a music appreciation course, providing a basis for understanding the development of music of various genres and an ability to recognize various musical qualities that became the basis for the development of sacred music. A background in music or the ability to read music is not a prerequisite, but is helpful.

Primary texts for purchase:

The Enjoyment of Music by Joseph Machlis; paired with the Norton Anthology of Western Music, together with other examples drawn from independent sources.
