What is Roman Numeral Analysis?

Roman numeral analysis is a way to represent chords based on the key signature. The Roman numeral shows the degree of the key that serves as a root for the chord. For instance, if you use the key of C, the first Roman numeral I will be a C. Then II will be a D, the III an E and so on.

Here is an image of the complete C major scale, with notes, jazz and Roman numeral notation.
