Roman Numeral Notation

Lesson 11 Chapter 1

Roman numeral notation in music is a quick way of communicating a song's chord sequence to yourself or to other musicians. As opposed to saying "this song goes from a D major, to a B minor, then to a G major and an A major", we can say "this song is in the key of D, and is a one six four five", and other musicians will understand you. That's the hope, at least 🙂

In this lesson I explain roman numeral notation, how to understand it, and I give several examples of how we can use roman numeral notation to communicate songs. 

This is a prerequisite to understanding song forms, or song templates, which are popular chord progressions.
