# in sync (harmony)

*Ordinarily means:* People are acting together smoothly without conflict.

A state where the interaction of parts produces a regular pattern that persists through time, even though no single part contains the whole pattern, and the boundary of the whole is not the same as the boundary of any part.

## Emergence
**Emerges from:** [interaction](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-interaction.process), [pattern](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-pattern.regularity), [persist](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-persist.continue), [boundary](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-boundary.limit), [part](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-part.relation), [whole](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-whole.complete)

**Through:** interaction.process

**Novel properties:**
