m.n giúp e vs There are three main periods in Beethoven's music career: early, middle and late. The beginning of his early period was in 1792 when he moved to Vienna, Austria. Beethoven quickly made a name for himself as a talented pianist. His compositions during this period consisted mainly of works for his main instrument, the piano, and were classical in nature. However, Beethoven's hearing was beginning to deteriorate during this period, and he tried to hide this fact from those around him. In 1800, Beethoven turned from the classical forms of the previous century to a more expressive or romantic music. His musical imagination began to grow beyond that of the piano.The middle period was believed to be Beethoven's greatest and most productive stage. In less than a decade, he produced countless masterpieces in every genre. In 1809, however, his musical creativity began to decline, possibly due to his health problems and mental state. Beethoven stopped conducting and performing in public, but continued to compose - many of his most admired works were created during this period. By 1815, he was almost completely deaf and his manners became increasingly rude. In 1827, he died after a long illness. Nearly 20,000 people lined the streets of Vienna to pay their last respect to the composer who had changed the music scene of Western Europe.
