Transforming Songs into Swing Jazz Style

Overview

This guide provides a systematic approach to converting any song (pop, folk, traditional) into authentic 1920s-1940s Lindy Hop-style swing jazz.

The Transformation Process

Phase 1: Analysis

Step 1: Document Original Song Structure

- Key and time signature
- Tempo (BPM)
- Form (verse, chorus, bridge)
- Chord progression
- Melody (with original notes)
- Lyrics

Step 2: Identify Core Elements

Phase 2: Tempo & Feel Adjustment

Lindy Hop Tempo Guidelines

Original Feel Target Swing Tempo
Ballad (60-80) Slow swing (110-120)
Medium (90-110) Medium swing (130-150)
Upbeat (120-140) Up-tempo swing (150-170)
Fast (150+) Fast swing or Balboa (170-200)

Establishing Swing Feel

Phase 3: Harmonic Reharmonization

Basic Chord Upgrades

Original Jazz Equivalent
C Cmaj7 or C6
Cm Cm7 or Cm6
G G7 (if dominant function) or Gmaj7
Dm Dm7
F Fmaj7 or F6

Adding Jazz Progressions

Insert ii-V-I Movements

Before a target chord, add its ii-V:

Original:  | C    | C    | F    | F    |
Jazz:      | C    | Gm7 C7 | F    | Cm7 F7 |
Rhythm Changes Substitution

For static chord sections, use I-VI-ii-V:

Original:  | C    | C    | C    | C    |
Jazz:      | Cmaj7 | Am7  | Dm7  | G7   |
Tritone Substitution

Replace V7 with bII7:

Original:  | Dm7  | G7   | C    |
Jazz:      | Dm7  | Db7  | Cmaj7 |
Chromatic Passing Chords

Add chromatic movement:

Original:  | C    | Dm   |
Jazz:      | C    | C#dim | Dm7  |

Common Reharmonization Formulas

For Static Major Chord (4 bars)
| Imaj7 | vi7  | ii7  | V7   |
For V-I Motion
Original: | G7   | C    |
Options:
1. | Dm7 G7 | Cmaj7 |          (add ii)
2. | Db7    | Cmaj7 |          (tritone sub)
3. | Dm7 Db7| Cmaj7 |          (ii + tritone)
4. | Ab7 G7 | Cmaj7 |          (chromatic approach)
For Minor Progressions
Original: | Am   | Am   |
Jazz:     | Am7  | Am7 E7b9 | (add V of vi)

Phase 4: Instrument-Specific Arrangements

Contrabass Part

  1. Identify new chord progression
  2. Map root movement
  3. Create walking bass line (see bass guide)
  4. Add approach notes between chords
  5. Write out first pass, then allow improvisation

Saxophone Part

  1. Transpose melody to sax key
  2. Identify melody's chord tones vs. passing tones
  3. Add swing phrasing marks
  4. Suggest fills between vocal phrases
  5. Create solo section chord chart

Rhythm Guitar Part

  1. Simplify chords to shell voicings
  2. Write chord chart with slash notation
  3. Mark any specific rhythmic figures
  4. Note dynamics (softer under vocals)
  5. Indicate any breaks or stops

Keyboard Part

  1. Choose voicing style (stride for solo, comping for ensemble)
  2. Write left hand chord voicings
  3. Mark comping rhythm suggestions
  4. Create intro/outro figures
  5. Note solo section length and changes

Vocals

  1. Transcribe melody in concert pitch
  2. Mark phrasing and breath points
  3. Suggest melodic variations for repeats
  4. Indicate scat sections (if any)
  5. Note dynamics and expression

Phase 5: Arranging the Form

Standard Swing Arrangement Form

INTRO:      4-8 bars (usually ii-V-I or piano/bass feature)
HEAD 1:     Full melody (vocals or unison horns)
HEAD 2:     Repeat with variations (optional)
SOLOS:      1-2 choruses each instrument
SHOUT:      Arranged section, building energy
HEAD OUT:   Return to melody
OUTRO:      Tag ending or ritard to final chord

Common Pitfalls to Avoid

  1. Over-complicating harmony - Keep it danceable
  2. Wrong tempo - Too slow kills the swing
  3. Ignoring the melody - Keep the hook recognizable
  4. Too many solos - Balance features with ensemble
  5. Weak endings - Plan the ending carefully
