According to Wikipedia:
The Symphony No. 9 in D minor, Op. 125 (sometimes known simply as "the Choral"), is the final complete symphony of Ludwig van Beethoven (1770–1827). Completed in 1824, the symphony is one of the best-known works of the repertoire of classical music. Among critics, it is almost universally considered to be among Beethoven's greatest works, and is considered by some to be the greatest piece of music ever written.
Why? I have listened to the the 9th symphony, but I don't think it it so great to be called "the greatest peice of music ever written". Are some other pieces of music not greater than the ninth symphony? According to me, Fur elise is much better than the ninth symphony. What is the reason behind calling the 9th symphony so great?
