# harmony (relational)

Several systems whose windows overlap across the region they jointly occupy, so that each system's ordinary drift keeps the others within their windows.

- Computed level: L15 (depth in the emergence graph, not abstraction)

## Emergence
**Emerges from:** [window](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-window.range), [drift](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-drift.aimless), [parameter](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-parameter.condition), [boundary](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-boundary.limit), [maintenance](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-maintenance.upkeep), [across](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-across.spatial), [keep](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-keep.maintenance), [occupied](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-occupied.spatial), [others](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-others.distinct-entities), [region](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-region.spatial), [several](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-several.quantity), [system](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-system.organized)

**Through:** The systems' overlapping condition windows allow mutual tolerance of aimless drift, enabling coexistence within a shared spatial region where each sustains its parameters through upkeep.

**Novel properties:**
- mutual tolerance of drift
- shared spatial persistence
- interdependent stability

## Examples
- The International Space Station maintains attitude control using gyroscopes and thrusters to counteract orbital drift. *(engineering)*
- Neurons in the human brain synchronize firing patterns through inhibitory and excitatory signals, sustaining stable network rhythms. *(biology)*
- The Federal Reserve adjusts interest rates in response to inflation trends to keep the economy within targeted growth windows. *(economics)*
