One of the things I always wonder about with these massive choirs with 10-30 thousand singers is how do you synchronize everyone so that it doesn't sound like a muddled mess? With such a large group the audio delays due to the speed of sound from the front to back or side to side of the choir start to become non-negligible.

Apparently 5 people per square meter is possible; so 2000 square meters is not that big. https://www.gkstill.com/Support/crowd-density/CrowdDensity-1...
