Gottfried Weber's description of the Roman numerals employed on each degree of the major and minor scales, triads at the left and sevenths at the right. Versuch einer geordneten Theorie der Tonsetzkunst, vol. II, p. 45.
The leading-tone and major V which contains it are also not used, as they are not part of the Aeolian mode (natural minor scale). However, Aeolian harmony may be used with mode mixture. For example, ♭ VII is a major chord built on the seventh scale degree, indicated by capital Roman numerals for seven.
For instance, in the C major scale, G is the fifth note of the scale, and the seventh chord built on G is the dominant seventh chord, G 7 (shown above). In this chord, F is a minor seventh above G. In Roman numeral analysis, G 7 would be represented as V 7 in the key of C major.
When used with chord symbols, the Roman numerals represent the root of a triad built on the associated scale step. In music theory based on the practices of the common practice period and its derivations the chord numerals are often written in upper case for chords in the major family, and in lower case for chords in the minor family, with the usual "m" or "—" minor chord quality suffix ...
In music theory, the scale degree is the position of a particular note on a scale [1] relative to the tonic—the first and main note of the scale from which each octave is assumed to begin. Degrees are useful for indicating the size of intervals and chords and whether an interval is major or minor .
The Modified Mercalli Intensity scale shows how intense an earthquake is at a specific site, based on what people on the ground would feel. The scale is expressed in Roman numerals. The scale is ...
In some conventions (as in this and related articles) upper-case Roman numerals indicate major triads (e.g., I, IV, V) while lower-case Roman numerals indicate minor triads (e.g., I for a major chord and i for a minor chord, or using the major key, ii, iii and vi representing typical diatonic minor triads); other writers (e.g., Schoenberg) use ...
The concept of harmonic function originates in theories about just intonation.It was realized that three perfect major triads, distant from each other by a perfect fifth, produced the seven degrees of the major scale in one of the possible forms of just intonation: for instance, the triads F–A–C, C–E–G and G–B–D (subdominant, tonic, and dominant respectively) produce the seven ...
