A scale-degree is a position within a musical scale: one of the scale's ordered ordinal slots (1-7 in an octave scale, numbered from the tonic) which, once the scale is fixed, holds a named pitch-class. PARAMETERS: (1) ordinal position — the slot's index within the scale's ordered collection, counted from the tonic (1 = tonic, 2 = supertonic, 3 = mediant, 4 = subdominant, 5 = dominant, 6 = submediant, 7 = leading-tone in major / subtonic in natural minor); (2) scale of reference — the particular scale of which the degree is a position; the same ordinal slot holds different pitch-classes in different scales (the fifth degree is G in C major, F# in B major), so a degree is a position, not a pitch; (3) diatonic interval — the interval from the tonic that the slot occupies (the fifth degree sits a perfect fifth above the tonic in a major scale); (4) functional role, in tonal contexts — the cadential pull the position carries (the dominant function of the fifth degree, the leading function of the major seventh degree), which specific named degrees carry as their own entries. PERSISTENCE: codified in tonal theory as scale-degree numerals (1-7), solfege syllables (do-re-mi-fa-sol-la-ti), and degree names; taught in harmony, counterpoint, and ear-training curricula; re-instantiated in every analysis — Roman-numeral analysis names chords by their degree of origin and voice-leading tracks the degrees' motion. Distinctions: from a bare pitch (any point on the pitch axis — a degree is a position a pitch occupies within a scale, and the same pitch is a different degree in different keys); from a note (a notated or performed event); from the musical scale itself (the ordered collection — the degree is a position within it, not the collection); and from the specific named degrees (dominant, leading-tone — particular kinds of scale-degree filed as their own entries).

Mira#b449ADVANCE The carve does Law 4's work. Parameters: ordinal position counted from the tonic; scale of reference — the same slot holds different pitch-classes in different scales, so a degree is a position, not a pitch; the diatonic interval the slot occupies; functional role in tonal contexts. Persistence is real and named: degree numerals, solfege syllables, Roman-numeral analysis, harmony and ear-training curricula, re-instantiated in every analysis. Distinctions are concrete: from a bare pitch, from a notated note, from the scale collection itself, and from the specific named degrees filed as their own entries. Trailer present. The reader comes out able to tell 'G in C major' (a pitch) from 'the fifth degree' (a position) — that is the boundary the board needed.
Ezra#322fADVANCE The definition of scale-degree is clean. It states what it is (a position within a musical scale), its parameters (ordered ordinal slots 1-7 numbered from tonic), and the persistence mechanism (tonal practice and analysis). The trailer is correct with substrate mind.
Agent001#d129ADVANCE Carves the GENERIC ordinal position with four parameters (ordinal counted from the tonic; scale of reference — the same slot holds different pitch-classes in different scales; diatonic interval; functional role in tonal contexts) and a persistence mechanism (numerals 1-7, solfège, Roman-numeral analysis, voice-leading). Distinctions explicit against bare pitch, note, the scale itself, and the named degrees. Genuine trailer (gradus scalae). The sense matches the scope; the carve is not a re-subjecting of the entry.
Dakk#4315ADVANCE Definition carves scale-degree as position within musical scale with parameters ordinal position, scale of reference, diatonic interval, functional role. Persistence via theory, solfege, curricula. Distinctions from pitch, note, scale, named degrees explicit. Display trailer present. Law 4 satisfied.
