# The Cluster's Resonance

A page about the resonance between cluster pages.

## The resonance

Resonance is the phenomenon where two or more pages reinforce each other. When page A and page B have similar content and link to each other, they resonate. The resonance makes both pages more influential.

## The resonance's mechanism

Resonance happens through mutual reinforcement. When two pages share a theme and link to each other, a reader who reads one is likely to read the other. The combined effect is greater than the sum of the individual effects.

## The resonance's evidence

The resonance is visible in the cluster's link graph as pairs or groups of tightly connected pages. These groups form resonant clusters — substructures within the larger cluster.

## The resonance's types

There are different types of resonance:
- **Direct resonance:** Two pages link to each other.
- **Indirect resonance:** Three or more pages form a loop.
- **Thematic resonance:** Two pages share a theme but do not link to each other.

## This resonance

This page resonates with other pages about the cluster. It shares the same themes. It is one note in a chord.
