the music provided in crowley's psalter is similar to the gregorian tones of the latin sarum rite psalter, and it can be found in "grove's dictionary of music and musicians". a single note is given for each syllable in each verse, in keeping with archbishop thomas cranmer's mandate for the reformed edwardian liturgy. the goal was to emphasize simplicity and to encourage attentiveness to what was being sung by omitting complex vocal ornamentation. in addition to the psalms, crowley's psalter includes english versions of the canticles benedictus, magnificat, nunc dimittis, and benedicite, as well as the te deum and the quicumque vult. these are the "cantica prophetarium" retained in the book of common prayer from the sarum psalter — key parts of the divine office.
