When Beethoven first performed his Ninth Symphony, as he couldn’t hear the rapturous applause it received due to his deafness, one of his singers approached him and turned him around so that he could see the standing ovation he was receiving.
Beethoven overcame deafness by biting a metal rod attached to his piano to hear his work. It’s called bone conduction, and can also be used to help divers talk and hear underwater, and is also used by elephants to communicate.
A man was sentenced to 20 hours of Beethoven after being caught for playing rap music too loud, as an alternative to a full fine. He only lasted 15 minutes before leaving.
Beethoven hated authority and social rank (he was a commoner), so much that he would stop playing if aristocrats talked during his performances.
After conducting Symphony No. 9 stone deaf, Beethoven had to be physically turned around to see the audience applaud him (some waved handkerchiefs so he could visibly see their ovations).
Beethoven cut the legs off his piano and placed it on the floor to feel the vibrations.
