Xenakis.(Iannis Xenakis)

IN HIS BOOK The Origins of Knowledge and Imagination (1978) Jacob Brownowski has written:

I believe that we need to review the whole of our natural philosophy in the light of scientific knowledge that has arisen in the last fifty years. It really is pointless to go on talking about what the world is like (as much of philosophy does) when the modes of perception of the world which are accessible to us have so changed in character. And we become more and more aware that what we think about the world is not what the world is but what the human animal sees of the world. (1) Those who are deeply involved with the arts of our time will understand immediately the significance of Bronowski's deceptively simple observation. If recent art, music and literature teaches us anything it is that our understanding of the world is a reflection of the way in which we appropriate the things around us; that, in the end, what we understand is not what we perceive of the world, but rather, how we perceive it.

Composition, of course, is an act of exploration. What this exploration reveals (as it is undertaken time and time again by innumerable composers) is just how complex and seemingly contradictory our perceptions can be. Each new discovery reveals previously hidden dimensions. Each new work reveals the world from a different perspective, and represents one of many ways to give it meaning.

With the death of Iannis Xenakis on February 4, 2001, the music world lost one of its greatest explorers. Truly, for Xenakis, the process of composing was a process of investigation and discovery, an ongoing search for new sonic materials as yet untested as musical matter, and for new tools with which to engage those new materials within the artistic enterprise. I can think of few composers of the twentieth century who have so radically changed our way of thinking about music. In every one of his works we sense a passion for discovery, the discovery of previously hidden or even completely unimagined facets of our aural experience. When we allow his music into our lives, it rewards us in rich and unexpected ways.

Of all the changes that have swept across our musical landscape, it seems to me that none has been more significant than the simple fact that what we now accept as material for making music includes virtually anything that we hear in our daily lives. The joy of bringing new sounds into the world of music is truly one of discovery; the discovery of new and previously unimagined connections between things always believed unconnected. As we embrace the full diversity of sonic matter in the world and seek to integrate this diversity into our creative lives, we reconfigure our culture itself. For almost fifty years Xenakis's music has vivified this fact.
