Guillaume Bouzignac (c. 1587 – c. 1643) was a French composer.
He studied at the Cathedral of Narbonne until 1604, and was choirmaster at the Cathedrals of Angoulême, Bourges, Tours, and Clermont-Ferrand.
[2] His motets are highly distinctive: "Simply stated, there is no other music of the time that looks the same on the page or sounds the same as the motets of Bouzignac.
"[3] "One name in this period rises above those of his contemporaries for all sacred music, including Masses: that of Guillaume Bouzignac.
"[4] His dialogue motets, such as Unus ex vobis and Dum silentium, are small scale oratorios which anticipate Giacomo Carissimi, and then Marc-Antoine Charpentier (1643–1704) two generations later.
