In music theory, Roman numeral analysis is a type of musical analysis in which chords are represented by Roman numerals (I, II, III, IV, …). In some cases, Roman numerals denote scale degrees themselves. More commonly, however, they represent the chord whose root note is that scale degree.

How do you analyze Roman numeral chords?
The numeral indicates the scale degree (scale step) of the root of the chord. The format of the roman numeral indicates the chord quality, as follows: In major keys, I, IV, and V are major; ii, iii, and vi are minor; and the leading tone chord is diminished.
How do you do Roman numeral analysis in music?
There are four basic steps used to create a Roman numeral analysis in a piece of music:
- Stack the sonority into thirds.
- Identify the quality of the triad (or tetrad)
- Identify the name of the triad from the root (bottom note once stacked in thirds)
- Identify the position from the chord factor in the bass.
What are Roman numerals in chords?
In traditional music theory, Roman numerals (I, II, III, IV, and so on) represent both the degrees of the major scale and the chord quality of each chord. Uppercase Roman numerals represent major chords, while lowercase numerals represent minor chords.
How do you write triads in Roman numerals?
Upper-case numerals represent major triads. Lower-case numerals represent minor triads. Upper-case numerals with a small plus sign represent augmented triads. Lower-case numerals with a small circle represent diminished triads.
