The phenomenon of music is given to us with the sole purpose of establishing an order in things, including, and particularly, the co-ordination betwe… - Igor Stravinsky

For I consider that music is, by its very nature, essentially powerless to express anything at all, whether a feeling, an attitude of mind, a psychological mood, a phenomenon of nature, etc. Expression has never been an inherent property of music. That is by no means the purpose of its existence. If, as is nearly always the case, music appears to express something, this is only an illusion and not a reality. It is simply an additional attribute which, by tacit and inveterate agreement, we have lent it, thrust upon it, as a label, a convention – in short, an aspect which, unconsciously or by force of habit, we have come to confuse with its essential being.

Music's exclusive function is to structure the flow of time and keep order in it.

Much of the music is a Merzbild, put together from whatever came to hand. I mean, for example...the Alberti-bass horn solo accompanying the Messenger. I also mean the fusion of such widely divergent types of music as the Folies Bergeres tune at No. 40 ('The girls enter, kicking') and the Wagnerian 7th-chords at Nos. 58 and 74."
