Scales
Scale construction, formulas, and practice sequences for major, minor, pentatonic, blues, and modal scales.
Major and Minor Scales
Major scale formula
Whole-Whole-Half-Whole-Whole-Whole-Half
W W H W W W H
C major: C D E F G A B C
W W H W W W H
G major: G A B C D E F# G
D major: D E F# G A B C# D
F major: F G A Bb C D E F
Bb major: Bb C D Eb F G A Bb
Minor scale types
Natural minor (Aeolian):
W H W W H W W
A B C D E F G A
Harmonic minor (raised 7th):
W H W W H W+H H
A B C D E F G# A
Creates V7 chord (dominant with leading tone)
Characteristic: augmented 2nd (F→G#) — Middle Eastern sound
Melodic minor:
Ascending: W H W W W W H
A B C D E F# G# A
Descending: natural minor (classical rule)
Jazz: same ascending and descending
Pentatonic and Blues Scales
Pentatonic scales
Major pentatonic (5 notes, no half steps):
1 2 3 5 6
C D E G A (remove 4th and 7th from major)
Minor pentatonic (the workhorse):
1 b3 4 5 b7
A C D E G (remove 2nd and 6th from natural minor)
Relative relationship:
C major pentatonic = A minor pentatonic (same notes)
Minor pentatonic is the foundation of:
Blues, rock, soul, funk, hip-hop
Works over almost any chord in the key
The "safe" scale for improvisation
Blues scale
Minor pentatonic + blue note (b5):
1 b3 4 b5 5 b7
A C D Eb E G
The b5 (blue note) creates the characteristic blues tension
Bend up from b5 to 5 for classic blues feel
Extended blues scale:
1 2 b3 3 4 b5 5 6 b7
Mix major and minor — this is the full blues vocabulary
Other Important Scales
Modes and character
All modes use the SAME notes as a major scale, starting from different degrees:
C Ionian: C D E F G A B (major — happy)
D Dorian: D E F G A B C (minor with major 6th — jazzy)
E Phrygian: E F G A B C D (minor with b2 — dark, Spanish)
F Lydian: F G A B C D E (major with #4 — dreamy)
G Mixolydian: G A B C D E F (major with b7 — dominant, rock)
A Aeolian: A B C D E F G (natural minor — sad)
B Locrian: B C D E F G A (diminished — unstable)
Whole tone and diminished
Whole tone scale (all whole steps):
C D E F# G# A#
Symmetric — only 2 distinct whole tone scales exist
Dreamy, ambiguous, no resolution
Diminished scale (alternating W-H):
C D Eb F Gb Ab A B
Symmetric — only 3 distinct diminished scales exist
Used over diminished chords in jazz
Chromatic scale (all half steps):
C C# D D# E F F# G G# A A# B
12 notes, every semitone
Used for chromatic runs and passing tones
Scale Practice Patterns
Practice approaches
Sequential: 1-2-3-4-5-6-7-8-7-6-5-4-3-2-1
Thirds: 1-3, 2-4, 3-5, 4-6, 5-7, 6-8
Fourths: 1-4, 2-5, 3-6, 4-7, 5-8

Tempo progression:
Start at 60 BPM (quarter notes)
Increase by 5-10 BPM when clean
Target: 120+ BPM for fluency
All 12 keys:
Follow circle of fifths: C, G, D, A, E, B, F#/Gb, Db, Ab, Eb, Bb, F
Don't just practice easy keys
