There are four basic steps used to create a Roman numeral analysis in a piece of music:

1. Stack the sonority into thirds.
2. Identify the quality of the triad (or tetrad)
3. Identify the name of the triad from the root (bottom note once stacked in thirds)
4. Identify the position from the chord factor in the bass.

How do Roman numerals work in music theory?

In music, Roman numerals are used to represent chords, coordinating with scale degrees 1-7. For instance, “IV” denotes the chord built on the fourth degree of a scale. ... While scale degrees refer to single notes, Roman numerals refer to chords.

How do you find the roman numeral triads?

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.
