🎷 Introduction to Jazz Guitar Harmony
Jazz guitar harmony represents one of the most sophisticated and expressive approaches to the instrument. Unlike basic pop or rock guitar, jazz emphasizes complex chord voicings, extended harmonies, and intricate progressions that create rich, colorful musical landscapes.
🎵 What Makes Jazz Chords Different:
- Extended harmonies: 7ths, 9ths, 11ths, and 13ths
- Altered notes: b5, #5, b9, #9, #11
- Complex voicings: Close position, drop voicings, spread voicings
- Chord substitutions: Tritone subs, chromatic approaches
- Voice leading: Smooth movement between chord tones
- Functional harmony: Understanding chord relationships and progressions
Jazz guitar chord study develops not just your technical ability, but your musical ear and harmonic understanding. These skills transfer to all styles of music, making you a more complete musician and opening up creative possibilities you never knew existed.
🎯 Benefits of Learning Jazz Chords:
- • Harmonic sophistication: Elevate your musical compositions and arrangements
- • Improved ear training: Develop sensitivity to complex harmonic relationships
- • Technical advancement: Challenge your fretting hand with complex fingerings
- • Musical versatility: Apply jazz concepts to pop, rock, and other genres
- • Professional development: Essential for session work and jazz performance
🎼 Essential Jazz Chord Types
Seventh Chords - The Foundation
All jazz harmony begins with seventh chords. While pop music often uses triads (3 notes), jazz requires the seventh to create the sophisticated sound that defines the genre:
🎸 Major 7th Chords (maj7)
Formula: 1 - 3 - 5 - 7
Sound: Dreamy, floating, sophisticated
Use: I and IV chords in major keys
Example: Cmaj7 (C-E-G-B)
🎸 Dominant 7th Chords (7)
Formula: 1 - 3 - 5 - b7
Sound: Bluesy, tension, needs resolution
Use: V chords, creates movement
Example: G7 (G-B-D-F)
🎸 Minor 7th Chords (m7)
Formula: 1 - b3 - 5 - b7
Sound: Mellow, introspective, stable
Use: ii and vi chords, creates smooth flow
Example: Am7 (A-C-E-G)
🎸 Half-Diminished 7th (m7b5)
Formula: 1 - b3 - b5 - b7
Sound: Dark, mysterious, unstable
Use: viiø7 chords, creates tension
Example: Bm7b5 (B-D-F-A)
Extended Chords - Adding Color
Extended chords add notes beyond the seventh, creating increasingly sophisticated harmonic colors:
🎵 9th Chords
Add the 9th (same as 2nd but an octave higher) for a floating, spacious sound. Examples: Cmaj9, G9, Am9
🎵 11th Chords
Include the 11th (same as 4th but an octave higher) for complex, sophisticated harmonies. Examples: C11, Am11
🎵 13th Chords
The ultimate extension - includes the 13th (same as 6th but an octave higher). Examples: C13, G13
🎸 Jazz Guitar Voicings and Fingerings
Drop 2 Voicings
Drop 2 voicings are among the most important jazz guitar chord forms. They're created by taking a close position chord and "dropping" the second highest note down an octave:
🎯 Drop 2 Characteristics:
- String layout: Usually spans 4 strings with a skip in the middle
- Playability: More manageable than close position chords
- Sound quality: Clear separation of voices, good for comping
- Versatility: Can be inverted and moved around the neck
- Voice leading: Excellent for smooth chord progressions
Essential Voicing Examples
🎸 Cmaj7 Drop 2 (6th string root)
8th fret: 6th string (C)
9th fret: 4th string (E)
8th fret: 3rd string (G)
8th fret: 2nd string (B)
Smooth, jazzy sound
🎸 G7 Drop 2 (6th string root)
3rd fret: 6th string (G)
3rd fret: 4th string (B)
4th fret: 3rd string (D)
3rd fret: 2nd string (F)
Classic dominant sound
Shell Voicings - The Essentials
Shell voicings use just the essential notes (root, 3rd, 7th) and are perfect for comping in small groups or when you need to leave space for other instruments:
🎵 Shell Voicing Benefits:
- Simplicity: Easy to play and remember
- Clarity: No muddy or conflicting notes
- Mobility: Quick to change and move around
- Space: Leaves room for bass player and soloist
- Function: Clearly defines the harmonic function
Rootless Voicings - Advanced Harmony
Rootless voicings omit the root note, allowing the bass player to handle that function while the guitar focuses on color tones and extensions:
🎸 A-Type Rootless (3rd in bass)
Uses 3rd, 5th, 7th, 9th from bottom to top. Creates open, spacious sound perfect for ballads and medium tempos.
🎸 B-Type Rootless (7th in bass)
Uses 7th, 9th, 3rd, 5th from bottom to top. More stable sound, excellent for up-tempo playing and bebop styles.
🎼 Essential Jazz Chord Progressions
ii-V-I - The Heart of Jazz
The ii-V-I progression is the cornerstone of jazz harmony. Understanding and mastering this progression in all keys is essential for any serious jazz guitarist:
🎵 ii-V-I in C Major:
Dm7 - G7 - Cmaj7
Function: Pre-dominant - Dominant - Tonic
Movement: Creates strong sense of resolution and forward motion
Use: Found in virtually every jazz standard
Circle of Fifths Progressions
Jazz often uses progressions that move through the circle of fifths, creating strong harmonic motion:
🎵 "Autumn Leaves" Progression
Cm7 - F7 - BbMaj7 - EbMaj7 - Am7b5 - D7 - Gm
Classic example of circle of fifths movement in a jazz standard
🎵 "All The Things You Are" Bridge
FMaj7 - E7 - Am7 - D7 - GMaj7
Demonstrates modulation through ii-V progressions
Rhythm Changes
Based on "I Got Rhythm" by George Gershwin, this progression appears in countless jazz standards:
🎵 Rhythm Changes (A Section):
CMaj7 - Am7 - Dm7 - G7
Analysis: I - vi - ii - V (in C major)
Songs: "Anthropology," "Oleo," "Cotton Tail," hundreds of others
🎨 Altered Chords and Substitutions
Altered Dominant Chords
Altered dominant chords add tension and color by raising or lowering the 5th and 9th. These create more sophisticated resolutions and are essential for modern jazz:
🎸 Common Alterations:
- b5: Flatted fifth (tritone substitute)
- #5: Raised fifth (augmented sound)
- b9: Flatted ninth (dark, bluesy)
- #9: Raised ninth (Hendrix chord)
- #11: Raised eleventh (Lydian sound)
🎸 Practical Examples:
- G7alt: G-B-Db-F-Ab-Bb
- G7b9: G-B-D-F-Ab
- G7#5: G-B-D#-F
- G7#11: G-B-D-F-C#
Tritone Substitutions
Tritone substitution replaces a dominant chord with another dominant chord a tritone away. This creates smooth voice leading and sophisticated harmonic movement:
🎯 Tritone Sub Example:
Original: Dm7 - G7 - Cmaj7
Substituted: Dm7 - Db7 - Cmaj7
The Db7 substitutes for G7, creating a descending chromatic bass line
Chord Substitution Strategies
🎵 Diatonic Substitution
Replace chords with others that share common tones. Example: Am7 can substitute for Cmaj7 (both contain C, E, G)
🎵 Chromatic Approach
Use chords that approach target chords chromatically. Creates smooth voice leading and sophisticated sound.
🎵 Reharmonization
Completely replace the harmonic progression while maintaining the melody. Advanced technique for creative arrangements.
