Meanings

The notation labelling chords by their degree within a key using Roman numerals.

Historically documentedVerified fact
Labels each chord by its scale degree within the prevailing key.
Contexts: Music
Historically documentedVerified fact
Records function rather than sound, so the same numeral describes chords with entirely different notes in different keys — which is the point, because the analysis is about the relationship and not the pitches.
Contexts: Music
Historically documentedVerified fact
Case and added figures carry quality and inversion, so a single numeral can specify a chord completely without naming a single note.
Contexts: Music
