Dependencies

What this concept builds on and what it makes possible — derived from the atlas’s dependency, causal and structural relations, not from every related edge.

Foundations · builds on

Chord progressionenablesTonalityEstablished

Open Chord progression →

chord progression enables tonality.

Mechanism: Progressions establish and confirm a tonal centre.

Open Musical key →

tonality emerges from musical key.

Mechanism: Tonality is the sense of a home key established across a passage.

Open Harmony →

Harmony depends on Tonality.

Mechanism: Chord function is defined relative to a tonal centre.

Structural role & consequence

Interpreted from the current atlas graph — what the connections mean, not just how many there are.

  • Currently dark in the atlas: no key date stored · 3 of 3 of its relations lack claim-level evidence.

    atlas representation · Describes the current Thinking OS representation, not the state of the world.

  • Builds on 2 foundations (requires / depends-on / derived-from / emerges-from).

    structural · Structural graph analysis — not a claim of importance, causation or history.

  • Structural neighbourhood: 3 → 11 → 23 concepts reachable within 3 hops.

    structural · Structural reach — being reachable is not the same as being understood.

  • All 3 of its relationships stay within its own discipline — a field-specific concept in the current atlas.

    structural · Structural graph analysis — not a claim of importance, causation or history.

Strengths & constraints

Constraints

  • Evidence coverage currently thin in the atlas — few of its relationships carry claim-level evidence. atlas representation
  • No dated history stored — the atlas records no key date for this concept. atlas representation

Conditions

  • Its dependency reading rests on 2 foundation relations. structural
  • Read structurally — most of its relationships carry no external evidence yet, so claims here are graph-derived. structural

The scientific picture
  • Connects 3 other ideas across 3 disciplines.
  • Most of its connections are of the “Cause & effect” kind.

Derived from the graph’s real structure — observations, not a score.
