Tonality is the system humans built to organize musical sound around a central reference pitch (the tonic), establishing hierarchies of stability among the remaining pitches and chords. Its parameters are: the tonic pitch, the scale or mode selecting which pitches are in-use versus excluded, and the harmonic grammar governing chord progressions and their functional relationships. It persists through notation systems, tuning conventions, pedagogical tradition, and the cognitive habits of composers and listeners across musical cultures.

Definition
Why it is in scope
A perceptual and cognitive framework humans built to organize pitches into hierarchical relationships — a tonal center, scale degrees, consonance and dissonance gradients. Human-made as a system of categories, taught across musical cultures, and persists through notation, theory, and listening practice.

Tonality organizes musical pitches around a central reference. Remove pitch and tonality has nothing to organize — its entire structure of pitch hierarchies collapses. Pitch as a perceptual attribute exists independently of tonality, but tonality as a musical system requires pitch to operate.

Chroma features are designed for tonal analysis — they fold spectral energy into pitch-class bins specifically to support tonal classification and key detection. By design, chroma serves tonality's operation.

MFCC features are designed for tonal analysis — they encode the spectral envelope shape that determines pitch perception and tonal hierarchy. MFCCs fold spectral information into cepstral bins that correlate strongly with human tonal perception, making them ideal for key detection and tonal classification.
