what a composer is, now

作曲家とは何か、いま

I was taught what composition was. The composer writes a score. Pitches, durations, dynamics, expression. The performer reads the score and produces the sound. The audience hears the sound. The composer is the author of the structure that the performer realises.

Then sometime in the twentieth century, a second kind of composer emerged. The recording composer. This one did not write a score; they made a recording, and the recording itself was the work. The composer was responsible not for the structure of the music but for the actual sound — every grain, every reverb tail, every imperfection committed. The performer dissolved into the producer.

I have been both. Anime scores, written for performers. Pieces recorded, where every sound was authored by me. Both fit a settled definition of "composer", just on different sides of a line.

What I am moving toward now is something the existing categories don't quite hold. I am no longer writing the score, and I am no longer authoring the recording. I am authoring the generator — the system that produces sound when something else happens to it. The rotation of the earth, a move on a board, a listener's location, the spectrum of a passing voice. The sound itself is not mine; it is what the system does when the world passes through it.

This is not less authorship. It might be more. The decisions I make at the level of the generator — what is mapped to what, what is privileged, what is excluded, what sounds at all — these are decisions about how a listener will hear the world. Not "how a song will sound" but "what kind of listening this generator invites". The signature moves up a level of abstraction. The composer signs not the song but the relation between world and listener.

This is why the work feels lighter and heavier at once. Lighter, because no specific sound is my burden anymore. Heavier, because the world's contact with the listener is, in some small way, my decision. The gardener has more responsibility, not less, when they author the frame instead of every flower.

This is, I think, what a composer becomes in this period. Not a writer of music, not a producer of recordings, but an author of generators — and through them, a maker of relations between world and ear. The work is no longer a song. It is a slow, patient way of saying: listen like this.
