Inversion notation for Roman numeral analysis depicting both Arabic numeral and Latin letters. Anton Bruckner, who transmitted the theory to Schoenberg and Schenker, apparently did not use Roman numerals in his classes in Vienna. Simon Sechter, considered the founder of the Viennese " Theory of the degrees" ( Stufentheorie), made only a limited use of Roman numerals, always as capital letters, and often marked the fundamentals with letter notation or with Arabic numbers. More precisely, he introduced the usage of large capital numerals for major chords, small capitals for minor, superscript o for diminished 5ths and dashed 7 for major sevenths – see the figure hereby. Gottfried Weber's Versuch einer geordneten Theorie der Tonsetzkunst (Theory of Musical Composition) (1817–21) is often credited with popularizing the method. He mentioned them also in his Handbuch zur Harmonielehre of 1802 and employed Roman numeral analysis in several publications from 1806 onwards. Soon after, Abbé Georg Joseph Vogler occasionally employed Roman numerals in his Grunde der Kuhrpfälzischen Tonschule in 1778. The earliest usage of Roman numerals may be found in the first volume of Johann Kirnberger's Die Kunst des reinen Satzes in 1774. The system came about initially from the work and writings of Rameau’s fundamental bass.Īrabic numerals have been used in the 18th century for the purpose of denoting the fundamental bass, but that aspect will not be considered here. Roman numeral analysis is based on the idea that chords can be represented and named by one of their notes, their root (see History of the Root (chord) article for more information). Versuch einer geordneten Theorie der Tonsetzkunst, vol. 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. Roman numerals thus abstract chord progressions, making them independent of key, so they can easily be transposed. On the other hand, in the key of A major, the I 7, IV 7, and V 7 chords would be A 7, D 7, and E 7. So the I 7, IV 7, and V 7 chords are C 7, F 7, and G 7. In the key of C major, the first scale degree ( tonic) is C, the fourth ( subdominant) is F, and the fifth ( dominant) is a G. For instance, the standard twelve-bar blues progression uses the chords I (first), IV (fourth), V (fifth), sometimes written I 7, IV 7, V 7, since they are often dominant seventh chords.

In pop, rock, traditional music, and jazz and blues, Roman numerals can be used to notate the chord progression of a song independent of key. In Western classical music in the 2000s, music students and theorists use Roman numeral analysis to analyze the harmony of a composition. However, some music theorists use upper-case Roman numerals for all chords, regardless of chord quality. Typically, uppercase Roman numerals (such as I, IV, V) are used to represent major chords, while lowercase Roman numerals (such as ii, iii, vi) are used to represent minor chords (see Major and Minor below for alternative notations). For instance, III denotes either the third scale degree or, more commonly, the chord built on it. More commonly, however, they represent the chord whose root note is that scale degree. In some cases, Roman numerals denote scale degrees themselves. In music theory, Roman numeral analysis is a type of musical analysis in which chords are represented by Roman numerals (I, II, III, IV, …).

Using lead sheet chord names, these chords could be referred to as A minor, D minor, G major and C major. The chord progression vi–ii–V–I in the key of C major.
