From 《The Music of Man》 (5)

After many a concert I have been asked what the music I played "means" to me; we have had to develop an elaborate set of terms to describe what music "means". The key difference lies in the fact that words refer first and foremost to the real world outside of us, to things and actions for which they serve as useful, acceptable symbols. Music, on the other hand, has a special relationship to our inner being. Our feelings become entities in themselves apart from literal meaning, and music shapes and alters them.
