What is the Roman numeral for 500?
Roman numeral analysis E, F, G, A, B), the first scale degree (Tonic) is C, the fourth (Subdominant) is F, and the fifth (Dominant) is a G. So the I, IV, and V chords are C, F, and G. In the same progression in the key of A (A, B, C, D, E, F, G), the I, IV, and V chords would be A, D, and E. Roman numerals thus abstract chord progressions, making them independent of the key, so can easily be transposed. Roman numeral analysis is the use of Roman numeral symbols in the musical analysis of chords. In music theory
Roman numeral analysis Roman numeral analysis In music, Roman numeral analysis uses Roman numerals to represent chords. The Roman numerals (I, II, III, IV, ...) denote scale degrees (first, second, third, fourth, ...); used to represent a chord, they denote the root note on which the chord is built. For instance, III denotes the third degree of a scale or the chord built on it. Generally, uppercase Roman numerals (such as I, IV, V) represent major chords while lowercase Roman numerals (such as i, iv, v) represent minor chords (see Major and Minor below for alternative notations); elsewhere, upper-case Roman numerals are used
