The building is surrounded by rows of slender white pillars totaling 823. These thin “columns” not only conceal the real volume of the building and evoke poetic associations with the forest, but also serve for the “initiation” of the public, as conceived by the architect, before entering the “kingdom of music”. This ephemeral façade creates a "light envelope" around the auditorium.
The arrangement of the pillars simultaneously along the ellipsoids and the radii of the circular building plan corresponds, according to Portzampark, "to both mathematical and musical principles."
In order to revive the walls of the auditorium, to connect the audience and art more closely, as in the theaters of the Shakespearean era, the boxes are arranged in many tiers, which should also resemble “skyscrapers around a busy square”.
