Music, which should pulsate with life, needs new means of expression, and science alone can infuse it with youthful vigor.

I have just begun a work in which an important part is given to a large chorus and with it I want to use several of your instruments - augmenting their range as in those I used for my Equatorial - especially in the high range.

The beginning of art is not reason. It is the buried treasure of the unconscious...that unconscious which has more understanding than our lucidity.

I do not write experimental music. My experimenting is done before I make the music. Afterwards it is the listener who must experiment.

In every domain of art, a work that corresponds to the need of its day carries a message of social and cultural value. It is the artist who crystallizes his age ... who fixes his time in history.

The present day composer refuses to die.

I dream of instruments obedient to my thought and which with their contribution of a whole new world of unsuspected sounds, will lend themselves to the exigencies of my inner rhythm.
