Perhaps I had better begin by explaining that I think of myself as a composer of music and not as a writer about music. This distinction may not seem important to you, especially when I admit to having published several books on the subject. But to me the distinction is paramount because I know that if I were a writer I would be bubbling over with word-ideas about the art I practice, instead of which my mind - and not my mind only but my whole physical being - vibrates to the stimulus of sound waves produced by instruments sounding alone or together. Why this is so I cannot tell you, but I can assure you it is so. Remembering then that I am primarily a composer and not a writer, I shall examine my subject mostly from the composer's standpoint in order to share with others, in so far as that is possible, the varied pleasures to be derived from experiencing music as an art.
