Recent research has proved that a number of Caustun’s church compositions were contrafacta (arrangements, usually involving text substitution) of works by his English and Continental contemporaries: Yield unto God is no exception, for some passages have been culled from the music of the Flemish composer Philippe van Wilder. The text is a lesser-known metrical adaptation of Psalm 150 that was divided by the composer into three sections, each set to the same music. This anthem probably dates from the reign of Edward VI and closely follows the edict of Archbishop Cranmer, who decreed that all new Anglican music 'would not be full of notes, but, as near as may be, for every syllable a note.' Caustun’s setting is strictly syllabic throughout, with passages of chordal writing relieved by points of unpretentious imitation. It can serve as an anthem or be sung in place of the psalm at Matins or Evensong.
