As an improvising musician, I am not in the music business, I am not in the creativity business; I am in the surrender business. Improvisation is acceptance, in a single breath, of both transience and eternity. We know what might happen in the next day or minutes, but we cannot know what will happen. To the extent that we feel sure of what will happen, we lock in the future and insulate ourselves against those essential surprises. Surrender means cultivating a comfortable attitude toward not-knowing, being nurtured by the mystery of moments that are dependably surprising, ever fresh.
