Written in 1919 by Marcel Dupré (1886-1971), this collection of organ works was originally titled Fifteen Pieces for Organ Founded on Antiphons (15 Versets pour les Vêpres du Commun des Fêtes de la Sainte Vierge). It is divided into three sections: Antiphons (1-5), Ave Maris Stella (1-4), and Magnificat (1-6).
