O magnum pietatis opus alleluia

The inventory for F-SO 596 was prepared by Alison Altstatt (University of Northern Iowa School of Music) with the permission of the Abbey of St. Pierre de Solesmes. Proofreading by Alessandra Ignesti (Dalhousie University). Transcription assistance was provided by Lauren Purcell Joiner and Gabriel Forero Villamizar. Support for this project was provided by the University of Northern Iowa School of Music, the College of Humanities, Arts, and Sciences, and Graduate College, the Beinecke Library of Yale University, and the National Endowment for the Humanities. All chants have been transcribed in both standardized and manuscript spellings. Rubrics have been added in the indexing notes. Stational liturgies have been indexed according to the feast on which they occur, as opposed to the saint at whose altar they were sung. In such cases, a clarifying note has been added in the indexing notes.
