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.

Musical intervalis derived fromHarmonic ratioEstablished

Open Harmonic ratio →

musical interval is derived from harmonic ratio.

Mechanism: An interval is heard as the frequency ratio between two tones, e.g. 3:2 for a perfect fifth.

Chordemerges fromMusical intervalEstablished

Open Chord →

chord emerges from musical interval.

Mechanism: A chord is formed by stacking intervals above a root note.

Transpositionis derived fromMusical intervalEstablished

Open Transposition →

transposition is derived from musical interval.

Mechanism: Transposition adds one fixed interval to every pitch.

System context

Musical intervalis part ofMusical scaleEstablished

Open Musical scale →

musical interval is part of a musical scale.

Mechanism: A scale is built by stacking a fixed pattern of intervals.

Open Semitone →

semitone is a kind of musical interval.

Mechanism: A semitone is the unit interval from which larger intervals are counted.

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 · 5 of 5 of its relations lack claim-level evidence.

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

  • Builds on 1 foundation (requires / depends-on / derived-from / emerges-from).

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

  • Structural neighbourhood: 5 → 19 → 48 concepts reachable within 3 hops.

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

  • All 5 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 1 foundation relation. structural
  • Read structurally — most of its relationships carry no external evidence yet, so claims here are graph-derived. structural

Seen through each discipline

How this concept sits in each of its fields — derived from its real connections in the graph, not asserted.

Concepts that look related but are not yet connected here — candidates for a connection to reason about, not established links.

The scientific picture
  • Connects 5 other ideas across 3 disciplines.
  • Most of its connections are of the “Kind & structure” kind.

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