Beethoven has always been one of the most fascinating artists to me. Though he wasn't born deaf, he became deaf at such a tender age that he had no way of truly comprehending the way sound interrelates. Yet, he did anyways. He understood sound in a way that very few have ever understood, and with a disability that would be assumed greatly inhibiting to such an art. I have lived with a lot of adversity in my life and I admire Beethoven for not letting life get the best of him and his passion. Fur Elise was actually the first song I learned to play on both the guitar and piano, and since Beethoven couldn't hear, I learned to play them without sheet music. I wanted to feel what he felt. Interestingly enough I did better figuring it out on the guitar than the piano. His music has such emotion and this has led to a reputation of being quite eccentric.
