The Fuhrerz Law

There's something called Fuhrerz Law, which is a law that was discovered in the 1860s by an Austrian doctor. When you ask people to guess tempos or lengths of time, people will always overestimate short durations of time and they'll always underestimate longdurations of time. So if we like 92 beats per minute, he was going to push his tempos to 108 - so it was just a little too fast. And this fits with what we know about the guy who wrote Beethoven: There are many psychological reasons why someone would want to write music at such a high tempo.
