# parametric composer
this document series develops a "super instrument" - a unified additive-synthesis engine capable of producing all sonic behaviors - and a "super composer" - a generative model of structured composition. all sound and behavior emerge from deterministic, hierarchical domains. these domains do not replicate existing musical traditions, but instead compose from structural first principles to produce both familiar and novel sonic behaviors.

the composition-layer configures what guiding values are provided and how they are projected. this resonates inside the potential-layer to generate structured event behavior prepared for final emission in sound by the sounding layer.

# composition
establishes the high-level conditions under which musical ideas unfold. it determines which patterns are selected, how they vary, and what global tendencies or constraints shape a piece's overall form.

```
# potential
interprets compositional intent into structured event behavior. it reads guide fields, applies deterministic processors, and prepares detailed event-domain descriptions-governing how, when, and why each event might occur.

## working-format
* `(activation start duration configuration)`
* example: `(activation start duration (pitch loudness character))`
* every parameter can be fixed or time-variant. for example, a scalar, an abstract path object, or an array of one factor per sample.

# sounding
resolves structured behavior into concrete signal-level parameters. this layer maps event descriptions to fully specified synthesis controls, transforming symbolic intent into audible form.
