Cortège et Litanie Op 19 No 2

This beautiful work is one of Dupré's most popular. The Cortège appears at the start, stated as a chorale of glowing beauty. Then the Litanie enters in a quiet single voice, and it sings its chant relentlessly for the remainder of the work, prompting Dupré's scholar Graham Steed to describe it as "the ecclesiastical equivalent of Bolero."
The fast movements at the end drove my polyphony and CPU indicators nearly into the red, showing that with Hauptwerk you surely need the fastest PC that you can afford.
