Scale Degrees
Notes are more than just letters. By giving each note a number, we unlock a universal map that works in every single key.
1. What is a scale degree?
A scale degree is simply the position of a note relative to the Root (also called the Tonic, or home base). We count from 1 to 7.
C = 1 D = 2 E = 3 F = 4
G = 5 A = 6 B = 7
Why numbers? Because "C" is not always the first note. In G Major, "G" is 1. In F Major, "F" is 1. But "1" is ALWAYS the home base.
Important: Degree 8 is the same as degree 1, just one octave higher.
Root/Tonic: The home note of the key.
Chord: Notes played together.
Triad: A 3-note chord (you build these in Lesson 11).
Progression: A sequence of chords in order.

The classic names
Musicians have given special titles to each degree based on its function (how it feels).
4. Roman Numerals
This is where numbers become powerful. We often use Roman Numerals to describe Chords built on these degrees.
Quick bridge: a triad is a 3-note type of chord. So when you see I, ii, V, you are often naming triads in that key.
The Major Scale Rule
Uppercase = Major Chord
Lowercase = Minor Chord
This pattern (Maj, min, min, Maj, Maj, min, dim) is true for EVERY Major Scale.
These Roman numeral labels describe diatonic triads in a major key (chords built only from that key's scale notes).
For now, treat this as a major-key rule. Minor-key Roman numeral patterns come in a later lesson.
5. Examples
G A B C D E F♯ G
1 2 3 4 5 6 7 1
6. Common Progressions
Scale degrees become powerful when you turn them into chord movement. Learn the number pattern once, then reuse it in any key.
Progression means chords played in a specific order. This is a preview; full progression writing comes after triads.
I - IV - V - I
vi - IV - I - V
I - IV - V - I = C - F - G - C
vi - IV - I - V = Am - F - C - G
I - IV - V - I = G - C - D - G
vi - IV - I - V = Em - C - G - D
In G major, ii = Am
Why: degree 2 is A, and ii is minor in a major key
Quick Review
- Scale degree: A note's number position relative to the root.
- Degree 1: Home base (tonic), no matter what key you are in.
- Roman numerals: A portable chord map you can move between keys.
- Major key chord pattern: I ii iii IV V vi vii°.
