Great music is that which penetrates the ear with facility and leaves the memory with difficulty. Magical music never leaves the memory.

Good music is very close to primitive language.

Good music is good no matter what kind of music it is.

I believe that music can be an inspirational force in all our lives — that its eloquence and the depth of its meaning are all-important, and that all personal considerations concerning musicians and the public are relatively unimportant — that music come from the heart and returns to the heart — that music is spontaneous, impulsive expression — that its range is without limit — that music is forever growing — that music can be one element to help us build a new conception of life in which the madness and cruelty of wars will be replaced by a simple understanding of the brotherhood of man. Music can be all things to all men. It is like a great dynamic sun in the center of a solar system which sends out its rays and inspiration in every direction. … It is as if the heavens open and a divine voice calls. Something in our souls responds and understands. We are speaking here of the most inspired music.

Music moves us because it serves as a metaphor for emotional life. It has peaks and valleys of tension and release. It mimics the dynamics of our emotional life.

So, music does not attempt to imitate Nature's sounds, but it does interpet and embody emotions awakened by Nature through a convention of its own, in a way to be aesthetically pleasing. In some such way, we, taking our hint from Nature, construct decoratively pleasing harmonies and symphonies of color expression of our sentiments.

If you read about African music, they believe that during the process of making this music that you come into contact with spirits from another plane. They say that this place is like a mirror of the world we live in…With the best music, you don't find the composer or the musicians within the work, you find yourself, your own feelings.

Why is some music so much deeper and more beautiful than other music? It is because form, in music, is expressive–expressive to some strange subconscious regions of our minds. The sounds of music do not refer to serfs or city-states, but they do trigger clouds of emotion in our innermost selves; in that sense musical meaning IS dependent on intangible links from symbols to things in the world–those 'things', in this case, being secret software structures in our minds.

Great music is a psychical storm, agitating to fathomless depths the mystery of the past within us.

Music at its best...is the grand archeology into and transfiguration of our guttural cry, the great human effort to grasp in time our deepest passions and yearnings as prisoners of time. Profound music leads us — beyond language — to the dark roots of our scream and the celestial
heights of our silence.

You could argue that there's maybe some mathematical interest in a Bach fugue, say, but the only thing that music does really well is "move" people -- make them feel something.

Music is associated not only with speculation but with morality. When rhythms and modes reach an intellect through the ear, they doubtless affect and reshape that mind according to their particular character.

The best music always results from ecstasies of logic.

Great music is in a sense serene; it is certain of the values it asserts. But it is also in terror, because those values are threatened, and it is not certain whether they will triumph in this world, and of course music is a missionary effort to colonise earth for imperialistic heaven.
