Was Beethoven involved in aleatory music?

He didn't "record" it on any sort of media device we're used to today. His sheet music was simply passed on.

Certainly is. It is played by many orchestra's in performance, and in solo concerts around the world. Just the other day, I heard a Beethoven piano sonata in a live concert.

The Classical era

Between classical and romantic Era. He is well known as a greatest composer during classical and romantic periods. Classical Era (1730-1820) Romantic Era (1815-1910)

At a young age his father learned to play piano and violin; so he taught Beethoven and often would help him rehearse.
