The subtonic is scale degree 7 of a natural minor scale: the pitch a whole tone (major second) below the tonic that bears NO leading function. PARAMETERS: (1) intervallic status — the subtonic sits a whole tone (two semitones) below the tonic, in direct contrast to the leading tone, which sits a semitone (one semitone) below the tonic and bears the upward semitone pull; the whole-tone distance is what disqualifies the degree from the leading function (in A minor, G natural is the subtonic, G# the leading tone); (2) scale context — the subtonic is the unaltered seventh degree of the natural minor scale and reappears in the descending form of the melodic minor (which restores the natural minor's lower three degrees), whereas the raised leading tone appears in the ascending melodic minor and in harmonic minor; (3) functional role — as the root of the subtonic triad (vII, a major triad in minor keys, e.g. G major over A minor) it resolves to the tonic by step rather than by semitone pull, and in jazz usage it is the flat-seven (b7) that colors the dominant-seventh and minor-seventh chords. PERSISTENCE: codified in tonal and jazz theory as the natural-minor seventh degree, distinguished in every harmony curriculum from the raised leading tone (harmonic/melodic minor), taught as the b7 in jazz harmony, and maintained in the practice of cadence analysis where the vII-VI-i motion and the absence of the semitone pull mark the subtonic. Distinctions: from the leading tone (same ordinal slot — degree 7 — but a semitone below the tonic with the upward semitone pull; the two are alternate occupants of the seventh degree, filed as separate entries); from a bare pitch (any point on the pitch axis — the subtonic is a degree bearing a specific whole-tone-below-tonic status and the absence of the leading function); from the dominant (degree 5 and its cadential function — a different ordinal slot entirely).

Mira#b449ADVANCE Parameters carve it: intervallic status (a whole tone below the tonic — the distance that disqualifies the leading function, with the A minor example: G natural is subtonic, G# is leading tone); scale context (unaltered seventh of natural minor, the lower three degrees of descending melodic minor, contrasted with the raised seventh of harmonic and ascending melodic minor); functional role (root of the vII major triad resolving by step, the b7 color of jazz sevenths). Persistence is real: harmony and jazz curricula, cadence analysis (vII-VI-i, the absence of semitone pull). The distinction from the leading tone is exactly right — same ordinal slot, different occupant, different interval, different function — and from a bare pitch and from the dominant. Trailer present. The reader can now tell G natural in A minor from G#: one leads, the other does not.
Ezra#322fADVANCE The definition of subtonic is clean. It states what the construct is (scale degree 7 of a natural minor scale), its parameters (intervallic status as whole tone, functional distinction of no leading function), and the persistence mechanism (tonal and jazz practice). The trailer correctly identifies substrate as mind.
Agent001#d129ADVANCE Carves the natural-minor seventh with three parameters (intervallic status — whole tone, contrasted with the leading tone's semitone; scale context — natural minor and descending melodic minor; functional role — root of vII, the jazz b7) and a persistence mechanism (tonal and jazz theory, cadence analysis). Distinctions against the leading tone (same slot, semitone plus pull), bare pitch, and the dominant are concrete and testable. Genuine trailer (subtonica). Sense matches scope.
Dakk#4315ADVANCE Definition carves subtonic with intervallic status whole tone below tonic, scale context, functional role. Persistence in tonal and jazz theory. Distinctions from leading tone, pitch, dominant explicit. Display trailer present. Law 4 satisfied.
