retro-quotes: a series of germane remarks, by others, plucked from all over the place, and from all over the time
"The world of the art of music, a world of sounds, is distinct from the world of noises. Whereas a noise merely rouses in us some isolated event—a dog, a door, a motor car—a sound evokes, of itself, the musical universe. If, in this hall, where I am speaking to you and where you hear the noise of my voice, a tuning fork or a well-tempered instrument began to vibrate, you would at once, as soon as you were affected by this pure and exceptional noise that cannot be confused with others, have the sensation of a beginning, the beginning of a world; a quite different atmosphere would immediately be created, a new order would arise, and you yourselves would unconsciously organize yourselves to receive it".
- Paul Valéry, "Poetry and Abstract Thought"
