Beethoven's Symphonies?

Question

Why do you think Beeyhoven composed 8 symphonies in 14 years and why his ninth symphony wasn't composted until ten years after his 8 symphony.

Answer 1

Because by the time he wrote the 9th symphony, he was completely deaf. In order to "hear" the chords and music, he had to put his ear on the floor to feel the vibrations of the chords. I think that would slow down the process considerably, don't you?
