Guillaume Bouzignac (*before 1587; † after 1643) was a French priest, choirmaster, and composer. He was born probably around 1587 in Saint-Nazaire-d'Aude in southern France. He received his education at Saint-Just Cathedral in Narbonne. His career is marked by professional travel which was common in his day; he is mentioned as a singer sous-maître and maitre de musique in Angoulême, Narbonne, Bourges, Paris, Rodez, and at Notre-Dame-du-Port de Clermont-Ferrand Cathedral, among other places.
It was not until the beginning of the 20th century that Bouzignac's works were rediscovered which were exclusively handwritten. It is not certain, but it is believed that Bouzignac spent some years in Italy and/or Spain after 1608. This would also explain the special characteristics of his music. What is striking about Bouzignac's compositional style is the special drama he achieves by dividing the choir into groups that interact with each other.
