The Ninth Symphony (Choral) was completed in 1823, by which time Beethoven was completely deaf. There was a poignant scene at the first performance. Despite his deafness, Beethoven insisted on conducting, but unknown to him the real conductor sat out of his sight beating time. As the last movement ended, Beethoven, unaware even that the music had ceased, was also unaware of the tremendous burst of applause that greeted it. One of the singers took him by the arm and turned him around so that he might actually see the ovation.
hiks sedih :'( beethoven is for sure exceptional. he would never stop - even deafness could not make him quit music. admirable!
