he number system is much more than a way to memorize chord progressions. Once you understand what each number represents, it can connect several areas of music theory at the same time.

In this quick lesson, I use a 4-5-3-4 progression in the key of G to show how one number can give you information about the notes, chords, scales, modes, arpeggios, and triads available to you.

You’ll learn how to:

• Understand what the numbers in a progression actually represent
• Connect numbers to chords, scales, and modes
• See the relationship between scales, arpeggios, and triads
• Use the number system as a form of musical shorthand
• Start thinking in musical relationships instead of isolated notes

The goal is to stop seeing all of these concepts as separate pieces of information and start seeing how everything connects.
