His music was so famous that many composers in the 19th century found it quite hard to compose because they thought they would be compared to him. For example, Johannes Brahms, took a long time to write his First Symphony. He thought that everyone was expecting him to be the next Beethoven. It was only towards the end of the 19th century that Gustav Mahler wrote several symphonies which include singing, although he does this very differently to Beethoven.
