A groove must be stated for a full phrase before it is developed

Spending the intro at low energy (0.1-0.3) for roughly 8-16 cycles before adding anything is a prerequisite for development. A groove the audience has not yet heard cannot be developed — there is no established expectation to subvert or reward. This mirrors the compositional principle of statement-before-variation: you cannot vary what has not been stated. In autonomous mode this means the intro section enforces a hold before any build action becomes valid.

Examples

A performer is 4 cycles into an intro at energy 0.2 with a target of 0.7. Adding a new layer now breaks the establish-before-build rule even though the arc calls for a build; the groove has not yet stated for a phrase.

Assessment

A student is 4 cycles into an intro at energy 0.2 with a target of 0.7. Should they start building immediately? Justify using the establish-before-build principle.

“**Establish before you build.** Spend the `intro` at low energy (0.1–0.3) letting one or two voices state the groove for a real phrase (~8–16 cycles) before adding anything.”
