Padre Fray Jaime Ferrer composed music on the six Lessons out of the Officium Defunctorum ad matutinum. The lessons in the Office of the Dead Matins/Officium defunctorum ad Matutinum consists out of nine short lessons. We found these six lessons set by Ferrer in the biblioteca de Real Monasterio de San Lorenzo de El Escorial Madrid and in the Catalogo del Archivo de Musica por Samuel Rubio, so far.
But these six lessons are not published as a cycle as erroneously stated in this website because they are published by Ferrer in different years. Certainly to the contrary we will here refer to the two real cycle-settings by Orlandus Lassus (1532-1594) Lectiones sacrae (1582) and Sacrae Lectiones (1560) which were discussed before on this website. The nine Lectiones/lessons are in general full part of the Office for the Dead from the eleventh Century until the Second Vatican Council in 1965. In 1965 substantial revisions and alterations of the total Office in the Catholic Church have been made. This Office of the Dead more specific these Lectiones would be read Ad Matutinum, in the morning prior to a Requiem Mass and the Burial-service and is published in the old liber Usualis (edition 1936 pages 1779-1799). All nine Lessons in the Service were normally followed by a Responsorium/Respond. See too our comments on the six lessons set by Pedro de Tafalla (1605-1660) and by Matias Cardona (1698-1755). Samuel Rubio (O.S.A.) (1912-1986) is the famous author of the Catálogo del Archivo de Música del Monasterio de San Lorenzo el Real Escorial.

Epilogue
We studied the catalogo del Archivo de Musica del monasterio de San Lorenzo de El Escorial por Samuel Rubio, MCMLXXVI. Rubio concluded on page 101 en 291 Jaime Ferrer wrote six Lecciones de los tres nocturnos de difuntos, a 8! Rubio which we discussed here above catalogued the following lessons out of the three Nocturns of the Dead: 1. Parce mihi, Domine ; 2. Manus tuae 3. Responde mihi 4. Quis mihi 5. Spiritus meus and 6. Quare de vulva. Jaime Ferrer (1762-1824), Pedro Tafalla (1605-1660), Matias Cardona ( 1798-1755) already mentioned who worked in the same Real Monastery San Lorenzo de Madrid have set the same six Lessons to music. Later we will see Antonio Soler ( 1729-1783) composed music on the same six Lessons, lecciones de difuntos . Moreover Soler was very prolific and he wrote about six bundles (lecciones or Officios called by Soller) containing the six mentioned lessons. It seems to us that in this Monasterio only six of nine lessons out of the Officium Defunctorum ad Matutinum are used in the Requiem services.
