Cantiones Sacrae (1589 and 1591)
Thirty-seven of Byrd's motets were published in two sets of Cantiones sacrae, which appeared in 1589 and 1591, along with 1592. Together with two sets of English songs, discussed below, these collections, dedicated to powerful Elizabethan lords (Edward Somerset, 4th Earl of Worcester and John Lumley, 1st Baron Lumley), probably formed part of Byrd's campaign to re-establish himself in Court circles after the reverses of the 1580s. They may also reflect the fact that Byrd's fellow monopolist Tallis and his printer Thomas Vautrollier had died, thus creating a more propitious climate for publishing ventures. Since many of the motet texts of the 1589 and 1591 sets are pathetic in tone, it is not surprising that many of them continue and develop the 'affective-imitative' vein found in some motets from the 1570s, though in a more concise and concentrated form. Domine praestolamur (1589) is a good example of this style, laid out in imitative paragraphs based on subjects which characteristically emphasize the expressive minor second and minor sixth, with continuations which subsequently break off and are heard separately (another technique which Byrd had learnt from his study of Ferrabosco). Byrd evolved a special 'cell' technique for setting the petitionary clauses such as ‘miserere mei’ or ‘libera nos Domine’ which form the focal point for a number of the texts. Particularly striking examples of these are the final section of Tribulatio proxima est (1589) and the multi-sectional Infelix ego (1591), a large-scale motet which takes its point of departure from Tribue Domine of 1575.
There are also a number of compositions which fail to conform to this stylistic pattern. They include three motets which employ the old-fashioned cantus firmus technique as well as the most famous item in the 1589 collection, Ne irascaris Domine the second part of which is closely modelled on Philip van Wilder's popular Aspice Domine. A few motets, especially in the 1591 set, abandon traditional motet style and resort to vivid word-painting which reflects the growing popularity of the madrigal (Haec dies, 1591). A famous passage from Thomas Morley's A Plaine and Easie Introduction to Practicall Musicke (1597) supports the view that the madrigal had superseded the motet in the favour of Catholic patrons, a fact which may explain why Byrd largely abandoned the composition of non-liturgical motets after 1591.
