Major and Minor Scales

Understanding Scales

Scales are organized sequences of notes that form the foundation of melody and harmony. The two most common types of scales in Western music are major and minor scales. Each has its own unique pattern of whole steps and half steps that give it a distinctive sound.

The Major Scale

The major scale has a bright, stable sound and is the foundation of Western music. It follows a specific pattern of whole steps (W) and half steps (H): W-W-H-W-W-W-H. This pattern creates the characteristic "happy" or "bright" sound of major scales.

Major Scale Pattern

Starting from any note, follow this interval pattern to build a major scale:

Root → W → W → H → W → W → W → H → Octave

Or in scale degrees: 1 - 2 - 3 - 4 - 5 - 6 - 7 - 8

C Major Scale

The C major scale uses only white keys on the piano, making it the easiest to visualize:

𝄞C4D4E4F4G4A4B4C5

Notes: C - D - E - F - G - A - B - C
Intervals: C→D (W), D→E (W), E→F (H), F→G (W), G→A (W), A→B (W), B→C (H)

Scale Degrees and Their Functions

Stable Tones (Consonant):

  • 1st (Tonic): Home base, most stable
  • 3rd (Mediant): Defines major quality
  • 5th (Dominant): Strong, stable

Active Tones (Dissonant):

  • 2nd (Supertonic): Tends to move to 1 or 3
  • 4th (Subdominant): Tends to move to 3
  • 6th (Submediant): Tends to move to 5
  • 7th (Leading Tone): Strongly pulls to 1

The Natural Minor Scale

The natural minor scale has a darker, more melancholic sound compared to major scales. Its pattern is: W-H-W-W-H-W-W. The key difference from major is the lowered 3rd, 6th, and 7th scale degrees.

Natural Minor Scale Pattern

Starting from any note, follow this interval pattern to build a natural minor scale:

Root → W → H → W → W → H → W → W → Octave

Or in scale degrees: 1 - 2 - ♭3 - 4 - 5 - ♭6 - ♭7 - 8

A Natural Minor Scale

A minor is the relative minor of C major (shares the same key signature - no sharps or flats):

𝄞A4B4C5D5E5F5G5A5

Notes: A - B - C - D - E - F - G - A
Intervals: A→B (W), B→C (H), C→D (W), D→E (W), E→F (H), F→G (W), G→A (W)

Types of Minor Scales

There are three forms of the minor scale, each with different characteristics:

1. Natural Minor (Aeolian Mode)

Pattern: W-H-W-W-H-W-W | Uses: ♭3, ♭6, ♭7

Most common in modern pop and rock music

2. Harmonic Minor

Pattern: W-H-W-W-H-1½-H | Uses: ♭3, ♭6, natural 7

Raises the 7th degree to create a stronger leading tone (used in classical music)

3. Melodic Minor

Ascending: W-H-W-W-W-W-H | Descending: Natural minor

Raises 6th and 7th ascending, returns to natural minor descending

Major vs. Minor: The Key Difference

The most important difference between major and minor scales is the third scale degree:

  • Major 3rd: 4 half steps from root (bright, happy sound)
  • Minor 3rd: 3 half steps from root (darker, sadder sound)
  • This single interval change creates the emotional difference between major and minor
  • All other scale degrees can be the same, but the 3rd is what defines the scale quality

Relative and Parallel Keys

Relative Keys

Relative major and minor scales share the same key signature but have different tonics. They contain the same notes but start on different scale degrees.

  • C Major and A Minor (no sharps/flats)
  • G Major and E Minor (1 sharp: F♯)
  • F Major and D Minor (1 flat: B♭)
  • To find relative minor: Go down 3 half steps from major tonic
  • To find relative major: Go up 3 half steps from minor tonic

Parallel Keys

Parallel major and minor scales share the same tonic note but have different key signatures and different notes.

  • C Major and C Minor (same tonic: C)
  • G Major and G Minor (same tonic: G)
  • A Major and A Minor (same tonic: A)
  • Parallel keys have different emotional qualities despite sharing the same starting note
  • Common in music for dramatic contrast (mode mixture)

Building Scales in Any Key

Once you understand the pattern, you can build major and minor scales starting from any note. Here's how:

Building a Major Scale

  1. Start with your root note
  2. Apply the pattern: W-W-H-W-W-W-H
  3. Add accidentals as needed to maintain the pattern
  4. Example: G Major = G-A-B-C-D-E-F♯-G

Building a Natural Minor Scale

  1. Start with your root note
  2. Apply the pattern: W-H-W-W-H-W-W
  3. Add accidentals as needed to maintain the pattern
  4. Example: D Minor = D-E-F-G-A-B♭-C-D
