Four Walls
Courtyards that enclose completely.
Courtyards close on four sides and open to the sky. Reflections arrive early and laterally with no ceiling to hold them, which is why speech and chamber forces sit well in Avignon and Aix while mass forces do not — and why the mistral is a programming constraint rather than a weather note.

The Cour de l'Archevêché
Gabriel Dussurget's 1948 choice at Aix — a small hard courtyard that suits a chamber orchestra and punishes a large one.

- 05
The Cour d'honneur
Jean Vilar put theatre in the Palais des Papes courtyard at Avignon in 1947; one flat facade, no roof, and a sound that became part of the work.

- 06
Reverberation in a box
Four hard walls and open sky make a room with strong lateral reflections and no ceiling to hold them.
