Choeur Seul. Par POULENC FRANCIS. The Litanies a la Viergne Noire signaled a new phase in Poulenc’s career, one marked by religious choral works of a mysterious, ethereal, and often extremely moving nature. Not surprisingly this was influenced by personal losses in his life. A beautiful work for female (SSA) voices, which features a modal, chant-like style, which avoids conventional cadences. Available here is the chorus part./ Répertoire / Choeur
