Contrabass / Upright Bass - Walking Bass Lines for Swing Jazz
Role in Swing Era
The double bass became a staple of the jazz rhythm section in the 1920s-30s, providing:
- Harmonic foundation - outlining chord roots and changes
- Rhythmic pulse - steady quarter notes driving the band
- Melodic interest - connecting chord tones smoothly
Key Historical Figures
- Wellman Braud (Duke Ellington) - early visibility, slapping technique
- Jimmy Blanton (Duke Ellington, 1939-41) - revolutionized bass as melodic voice
- Walter Page (Count Basie) - master of walking lines
- Milt Hinton - "Dean of Jazz Bass"
Walking Bass Line Fundamentals
What is a "Walking" Bass Line?
A continuous stream of quarter notes that:
- Outlines the chord progression
- Creates forward momentum ("swing")
- Provides harmonic and rhythmic foundation
- Sounds like "walking" - steady, connected movement
The Primary Rule
GROOVE FIRST, NOTES SECOND
- Focus on time and feel before harmonic choices
- Big, fully connected quarter notes
- Minimal space between notes
Basic Walking Bass Patterns
Beat Placement Principles
- Beats 1 & 3: Chord tones (root, 3rd, 5th) - "strong beats"
- Beats 2 & 4: Passing tones, approach notes - "weak beats"
Root-Based Approach (Beginner)
For any chord, start with:
Beat 1: Root
Beat 2: Passing tone
Beat 3: 5th (or root)
Beat 4: Approach note to next chord
Approach Notes (Chromatic & Diatonic)
Leading into the next chord root:
- Chromatic below: Half step below target
- Chromatic above: Half step above target
- Diatonic: Scale tone approach
- Double chromatic: Two half steps
Essential Patterns for ii-V-I
Pattern 1: Root-3rd-5th-Approach
Dm7: D - F - A - Ab (chromatic approach to G)
G7: G - B - D - C# (chromatic approach to C)
Cmaj7: C - E - G - (next chord approach)
Pattern 2: Root-5th-3rd-Approach
Dm7: D - A - F - F# (chromatic approach)
G7: G - D - B - B (leading tone to C)
Cmaj7: C - G - E - (continue)
Pattern 3: Descending
Dm7: D - C - B - A
G7: G - F - E - D#
Cmaj7: C - B - A - G
Chord Movement Patterns
Movement by 4th (Most Common)
When chord moves up a 4th (e.g., Cm7 to F7):
Ascending: C - D - Eb - E (to F)
or: C - D - E - E (to F)
Movement by 5th
When chord moves down a 5th:
Descending: G - F - E - Eb (to D)
Static Chord (One chord for 2+ bars)
Create melodic interest:
Bar 1: Root - 3rd - 5th - 6th
Bar 2: Root - 2nd - 3rd - approach
Swing Feel Tips
Articulation
- Legato: Notes connected, no gaps
- Slight accent on 2 & 4: Supports backbeat
- Consistent volume: Steady pulse
Time Feel
- Slightly behind the beat = "laid back" (swing feel)
- Right on the beat = solid foundation
- Avoid rushing (common amateur mistake)
Physical Technique (Acoustic Bass)
- Strong pizzicato with 1-2 fingers
- Pull string sideways, not up
- Let notes ring fully
- Optional: slapping technique for emphasis

Practice Exercises
Exercise 1: Root Movement
Play only roots in quarter notes through a tune's changes.
Exercise 2: Root-5th Pattern
Alternate root and 5th for each chord.
Exercise 3: Scale-Based Walking
Use chord scales to create stepwise motion.
Exercise 4: Approach Notes
Focus on smooth voice leading into chord changes.
Common Mistakes to Avoid
- Playing too loud - bass should support, not dominate
- Inconsistent time - use metronome practice
- Ignoring the drummer - lock with hi-hat on 2 & 4
- Too many notes - keep it simple and groovy
- Random note choices - outline the harmony clearly
Song-Specific Application
For any song:
- Identify the chord progression
- Map out root movement
- Add 5ths and 3rds on strong beats
- Connect with chromatic/diatonic approach notes
- Practice at slow tempo (60-80 BPM)
- Gradually increase to performance tempo
