Perhaps all music, even the newest, is not so much something discovered as something that re-emerges from where it lay buried in the memory, inaudible as a melody cut in a disc of flesh. A composer lets me hear a song that has always been shut up silent within me.
When Mozart was composing at the end of the eighteenth century, the city of Vienna was so quiet that fire alarms could be given verbally, by a shouting watchman mounted on top of St. Stefan's Cathedral. In twentieth-century society, the noise level is such that it keeps knocking our bodies out of tune and out of their natural rhythms. This ever-increasing assault of sound upon our ears, minds, and bodies adds to the stress load of civilized beings trying to live in a highly complex environment.
Music and dancing (the more the pity) have become so closely associated with ideas of riot and debauchery among the less cultivated classes, that a taste for them, for their own sakes, can hardly be said to exist, and before they can be recommended as innocent or safe amusements, a very great change of ideas must take place.
Since music is a language with some meaning at least for the immense majority of mankind, although only a tiny minority of people are capable of formulating a meaning in it, and since it is the only language with the contradictory attributes of being at once intelligible and untranslatable, the musical creator is a being comparable to the gods, and music itself the supreme mystery of the science of man, a mystery that all the various disciplines come up against and which holds the key to their progress.
The musical emotion springs precisely from the fact that at each moment the composer withholds or adds more or less than the listener anticipates on the basis of a pattern that he thinks he can guess, but that he is incapable of wholly divining. If the composer withholds more than we anticipate, we experience a delicious falling sensation; we feel we have been torn from a stable point on the musical ladder and thrust into the void. When the composer withholds less, the opposite occurs: he forces us to perform gymnastic exercises more skillful than our own.
