Today, consider polyphony and tonal range. What are all the voices that combine into your writing so far, whether strands of your own, or appearing via the mouths of characters. Does another voice need to join? Does the balance need to change?
Using the planetary metaphor, follow these questions by imagining something incoming, on an intersecting course with what you have made. Perhaps you access this tonal range by imagining a crash that causes your own accreting body of writing to split open and bring to the surface what was previously muffled.
Or perhaps you imagine it as something that lands on your writing, the way much of earth’s water came from icy asteroids. This thing merges with your writing, becomes one of its elements and influences its future without conflict or breaking what was already there; it adds itself to the number.
