I think he wrote the most symphonies than anyone else. he was also deaf when he did it. he started young but not as young as Mozart who started at 5. His pieces are really amazing. They are really complex and beautiful. If you want to buy some of his pieces try Moonlight Sonata, Fur Elise, Symphony No. 5. But really all of them are good so what ever ones you pick will be good.

If you seriously want to acquaint yourself then I suggest you read ‘Life Of Beethoven’ by Alexander Thayer..
It’s a voluminous work but very compelling and utterly brilliant.

He was a german composer slash piano player in the 18th century. he wrote famous songs like

*the moonlight sonata
* fur elise
* Beethoven’s Fifth Symphony

he was an amazing pianist because he composed a lot of his music being deaf! he lost his hearing in his twenties but made up concerts anyway by putting his head on the piano to get the vibes

I suggest you search the internet, starting with wikipedia.com. This question is far too extensive to deal with on this forum. There are many websites devoted to Beethoven – just google him.
