what impreses me in Beethoven's music

Answer 1

Have you listened to Beethoven's music? Any of it?

Only you can answer this question, but you have to have listened to several of his works to decide.

This is a good article on Beethoven, and at the bottom of the webpage, there are links to various recordings of some of his works.

Part way down the page is a Media section; click on each triangle in a circle to listen to three of his most famous works.
