The largest musical instrument in the world - a building with perfect acoustics, as described by a visitor "the guard was singing to show the acoustics. He had a sweet tenor tone, but the acoustics both amplified and blended the harmonics - while he sang one tone on my right, I heard previously sung harmonic tone on my left! To hear blended harmony from one singer was both awesome and eerie - in the sense that I kept looking for the ghostsinging on my left!" In this building, a singer at the center of the floor can sing in 4 part harmony with himself, a design unequaled since in modern architecture.
