PASSAGE – III:

If Bach is the mathematician of music, as has been asserted, Beethoven is its philosopher. In his work the philosophic spirit comes to the fore. To the genius of the musician is added in Beethoven a wide mental grasp, a selfless spirit that seeks to help humanity on the upward path.

Up to Beethoven's time musicians in general performed their work without the aid of an intellect for the most part; they worked by intuition. In everything outside their art they were like children. Beethoven was the first one having the independence to think for himself - the first to have ideas on subjects unconnected with his art. He it was who established the dignity of the artist over that of the simply well-born. His entire life was a protest against the pretensions of birth over mind. His predecessors, to a great extent subjugated by their social superiors, sought only to please. Nothing further was expected of them. This mental attitude is apparent in their work. The language of the courtier is usually polished, but will never have the virility that characterizes the speech of the free man.

As with all valuable things, however, Beethoven's music is not to be enjoyed for nothing. We must on our side contribute something to the enterprise, something more than simply buying a ticket to the performance. We must study his work in the right spirit, and place ourselves in a receptive attitude when listening to it to understand his message. Often metaphysical, particularly in the work of his later years, his meaning will be revealed only when we devote to it earnest and sympathetic study. No other composer demands so much of one; no other rewards the student so richly for the effort required. The making of a fact, the subject of thought vitalizes it. It is as if the master had said to the aspirant: "I will admit you into the ranks of my disciples, but you must first prove yourself worthy." An initiation is necessary; somewhat of the intense mental activity which characterized Beethoven in the composition of his works is required of the student also.
