Invokes the memory of Guido d'Arezzo associated with the sight-singing technique of the movable 'do' system.

A Prayer to St John the Baptist by Cecilia McDowall for SATB and Organ.Written for the 2018 BBC Advent broadcast sung by the choir of St John's College Cambridge A Prayer to St John the Baptist sets an artfully crafted text that combines Guido d'Arezzo's Ut queant laxis (itself a Hymn to John the Baptist as well as a medieval music-teaching mnemonic) with Thomas Merton's poem on the same subject. The Organ's flowing quavers represent Merton's baptismal 'rivers of water' while the largely octatonic melodies conjure a tellingly mysterious atmosphere.
