The Ghost

In 1808 the composer and violinist Louis Spohr was invited to a rehearsal in Beethoven's house of the D Major Piano Trio, Opus 70, No.1 known as The Ghost, and wrote of the occasion:

"It was not an enjoyable experience. First of all the  piano was dreadfully out of tune, which did not trouble Beethoven in the least, since he could not hear it. Little or nothing remained of the brilliant technique which had been so much admired. In loud passages the poor deaf man hammered away at the notes crashing through whole groups of them so that without the score one lost all sense of the melody. I was deeply moved by the tragedy of it all. Beethoven's almost continual melancholy was no longer a mystery to me."
