The premise is already wrong. No orchestra can play Beethoven's 9th symphony in 40 minutes, this piece is longer than an hour.
Maybe it's longer than an hour if only 80 players play it. This is 120!
I read that as one hundred twenty factorial. That's a LOT of players!
More players than atoms in the known universe
More players than you could shake a stick at!
...wait, ask the conductor first.
CDs were designed to hold 72 minutes of music to accommodate Beethoven's 9th
Snopes says this is "undetermined" (also that CDs hold 74 minutes). Honesty pleasently surprised by how plausible it is from the given evidence though, I was expecting this to turn out to be definitively a myth.
Yeah, just checked and the Wikipedia says it's a myth!
It also requires a chorus
I prefer a flanger and a 200 ms delay
