10A pitch set is only the first layer

Tunings & traditions

Different musical systems organize pitch through tuning, hierarchy, characteristic motion, phrase grammar, rhythm, form and performance practice. A keyboard mapping can be useful—but it is never the whole tradition.

Three different objects

ObjectWhat it specifiesWhat it does not specify
TuningAvailable or preferred frequency relationships.Which notes feel central or how a phrase moves.
Pitch inventoryA set of positions used in a context.Intonation, hierarchy, ascent/descent or ornament.
Phrase grammarCharacteristic approaches, emphases and directions.One universal scale formula detached from performance.

Repeated focus tones and directed approaches become more identifying than an ascending scale.

Why it fits
The implementation names exactly which layer it models and which layers remain missing.
