Major and Minor Scales

Learn about the most important scales in Western music and understand their relationships.

Understanding Major and Minor Scales

Major and minor scales form the foundation of Western music. Understanding their construction, characteristics, and relationships is essential for composing, improvising, and analyzing music.

The Major Scale

Construction

Formula: W - W - H - W - W - W - H

Scale Degrees: 1 - 2 - 3 - 4 - 5 - 6 - 7 - 8

Example: C Major: C - D - E - F - G - A - B - C

Characteristics:

  • Bright and stable sound
  • Foundation of Western harmony
  • Reference point for other scales
  • Used in most popular music

Minor Scales

Natural Minor

Formula: W - H - W - W - H - W - W

Scale Degrees: 1 - 2 - ♭3 - 4 - 5 - ♭6 - ♭7 - 8

Example: A Minor: A - B - C - D - E - F - G - A

Characteristics:

  • Dark, melancholic sound
  • Also called Aeolian mode
  • Parallel minor to C major
  • Common in folk and rock music

Harmonic Minor

Formula: W - H - W - W - H - W+H - H

Scale Degrees: 1 - 2 - ♭3 - 4 - 5 - ♭6 - 7 - 8

Example: A Harmonic Minor: A - B - C - D - E - F - G♯ - A

Characteristics:

  • Exotic, dramatic sound
  • Raised 7th degree
  • Creates strong dominant function
  • Common in classical and jazz

Melodic Minor

Formula: W - H - W - W - W - W - H (ascending)

Scale Degrees: 1 - 2 - ♭3 - 4 - 5 - 6 - 7 - 8 (descending uses natural minor)

Example: A Melodic Minor: A - B - C - D - E - F♯ - G♯ - A (ascending)

Characteristics:

  • Smooth melodic motion
  • Different ascending and descending
  • Combines major and minor qualities
  • Important in jazz improvisation

Major/Minor Relationships

Relative Major/Minor

Scales that share the same key signature

Example: C major and A minor

  • Minor starts on 6th degree of major scale
  • Same notes, different tonal center
  • Common modulation technique
  • Important for understanding harmony

Parallel Major/Minor

Scales that share the same tonic

Example: C major and C minor

  • Same tonic, different key signatures
  • Different notes but same root
  • Used for modal mixture
  • Creates dramatic contrast

Scale Degrees and Their Functions

Tonic (1)

Function: Home base, point of rest

Major Example: C in C major

Minor Example: A in A minor

Supertonic (2)

Function: Creates motion to dominant or tonic

Major Example: D in C major

Minor Example: B in A minor

Mediant (3)

Function: Defines major/minor quality

Major Example: E in C major

Minor Example: C in A minor

Subdominant (4)

Function: Creates motion away from tonic

Major Example: F in C major

Minor Example: D in A minor

Dominant (5)

Function: Creates tension, pulls to tonic

Major Example: G in C major

Minor Example: E in A minor

Submediant (6)

Function: Relative minor of major key

Major Example: A in C major

Minor Example: F in A minor

Leading Tone (7)

Function: Strong pull to tonic

Major Example: B in C major

Minor Example: G♯ in A harmonic minor

Practice Exercises
