Composed in 1942, Titelouze's tombstone by Marcel Dupré is a set of sixteen chorals for Organ. Based on liturgical rhythms, these chorals are rated easy and medium in term of difficulty. This musical memorial to Jehan Titelouze, an organist who lived at the period of the Spanish Armada (16th century), is a pedagogical work with melody mainly based on Gregorian music. These sixteen studies, all very different and very progressive are: 1. Creator Alme Siderum (3 voices - manuals only) 2. Jesu Redemptor Omnium (3 voices - manuals only) 3. A solis Ortus Cardine (3 voices) 4. Audi Benigne Conditor (3 voice) 5. Te Lucis Ante Terminum (4 voices) 6. Coelestis Urbs Jerusalem (4voices) 7. As Regias Agni Dapes (4 voices) 8. Veni Creator Spiritus (4 voices) 9. Vexilla Regis (4 voices) 10. Pange Lingua (3 voices) 11. Ave Maris Stella (4 voices) 12. Iste Confessor (4 voices) 13. Lucis Creator Optime (4 voices) 14. Ut Queant Laxis (5 voices) 15. Te Splendor et Virtus (5 voices) 16. Placare Christe Se rvullis (Toccata) Each choral of this set is really colourful and can be considered a masterpiece.
