Pier Francesco Valentini (c.1570-1654) was an Italian nobleman, amateur composer and music theorist.
His tour de force on the art of the contrapuntal canon was Canone nel modo Salomonis (1631) a 96-voice contrapuntal exercise which could be expanded to a symbolically significant 144,000 voices, singing at different speeds and in different metres.
[1] He also published more conventional madrigal and motet collections.
