Why focus on writing and try to define the concept of writing? I'll answer straight away: as far as I'm concerned, if I have to pass judgment on a score, on a composer, it's the essential criterion that determines me. A composer may or may not know how to write: this presents itself to my mind in almost equally categorical terms. If I were asked the question: can you make such a distinction even on the most recent scores? I would answer immediately: yes. Even in the most radical, most innovative, most unfamiliar idiom, I can detect, discern this phenomenon ofwriting. (Of course, the eye can tell more immediately than the ear about certain long-term parameters. Performance, however, if effective, gives instant information on the adequacy of writing and listening). And in a work that does not use traditional means, that can scarcely be transcribed except by rough diagrams from sound documents, in short, a work to which writing on paper has not pre-existed, can you still apply this category of writing? My answer is: yes; I can base my judgment on a "document" that doesn't necessarily require a paper transcription. The unfolding, the conjunction of events and the validity of the sound phenomenon are my guarantee ofwriting. Of course, the categories are not so distinct; but such criteria indicate works where the writing is unfinished, or inadequate.
I'll be judged presumptuous; but above all, I'll be asked: how can you be so sure, and on what basis can you establish that a work is written or not? Here, my answer becomes more vulnerable. For any argument, I can present intuition, habit and experience, which short-circuit any logical development. But if we try to define the basis of this intuition, to find precise and determined criteria, I'll remain perplexed before giving them, I don't even know if I'll be able to give an adequate description. I know I can rely on the writing, but that remains both very acute and excessively vague: I'll rely above all on the sense of relationship, of sequence, of development. Moreover, as it applies to works of different character and from different periods, the word "writing" cannot have exactly the same meaning or be applied in exactly the same way. On the other hand, it covers many different notions, from instrumental writing to the manipulation of language elements. What's more, it's a word that can't be applied more directly to literature of any kind, and is used for everything, even the most insignificant of purposes. We're talking about pictorial writing, architectural writing: none of the fields of invention is spared by this invasive word which, in the end, means nothing and means everything. It can therefore be seen as a key word, but also as the most banal cliché: a key word capable of unifying the various means of expression, however far apart they may be; a cliché because it cannot be applied specifically to anything. This concept of writing, however precise and decisive it may seem from afar, is as elusive, difficult and even impossible to pin down as it is when we approach it.
