How big was the scale of polychoral music? The biggest was a mass by Alessandro Striggio for 5 choirs of 12, totaling 60 independent polyphonic lines. Lassus, Malvezzi, Rossetto, and others wrote 30-50 part pieces. But the best known is Tallis’ Spem in alium for 40 voices (8 choirs of 5).
Spem in alium (Latin for "Hope in any other") is a 40-part Renaissance motet by Thomas Tallis, composed in c. 1570 for eight choirs of five voices each. It is considered by some critics to be the greatest piece of English early music. H. B. Collins described it in 1929 as Tallis's "crowning achievement", along with his Lamentations.[1]
The early history of the work is obscure, although there are some clues as to where it may have been first performed. It is listed in a catalogue of the library at Nonsuch Palace, a royal palace that was sold in the 1550s to the Earl of Arundel, before returning to the crown in the 1590s. The listing, dating from 1596, describes it as "a song of fortie partes, made by Mr. Tallys". The earliest surviving manuscripts are those prepared in 1610 for the investiture as Prince of Wales of Henry Frederick, the son of James I.
