Dom Alcuin Reid is a foremost authority on the Roman Rite. He has reviewed William Mahrt's Musical Shape of the Liturgy as follows:
Immersed in the tradition and standing in critical dialogue with the liturgical, musical and pastoral realities facing the Church at the beginning of the twenty-first century, William Marht’s The Musical Shape of the Liturgy is replete with practical and academic wisdom distilled from the liturgical turmoil of recent decades that no liturgist or liturgical musician can afford to ignore. In the quest for music that is truly liturgical, truly sacred, Marht’s contribution is prophetic and seminal.
