Theory Fundamentals

What Are Minor Sixth Chords?

  • Definition: Four-note chords combining a minor triad with a major 6th
  • Formula: Root + Minor 3rd + Perfect 5th + Major 6th (1-b3-5-6)
  • Interval Pattern: 3 semitones + 4 semitones + 2 semitones
  • Sound Quality: Bittersweet, sophisticated, nostalgic
  • Function: Tonic minor in jazz, melodic minor harmony

Musical Applications

  • Jazz: Tonic minor chord in jazz minor keys
  • Bossa Nova: Signature chord for Brazilian jazz
  • Film Noir: Dark, sophisticated underscore harmony
  • Swing: Classic big band minor voicings

Understanding Minor Sixth Chord Construction

Am6 Example

  • Root: A (1st degree)
  • Minor 3rd: C (b3rd degree)
  • Perfect 5th: E (5th degree)
  • Major 6th: F# (6th degree)
  • Result: Bittersweet, jazz-inflected minor

Interval Quality

  • Minor 3rd: Dark, emotional foundation
  • Perfect 5th: Stability and grounding
  • Major 6th: Brightness within minor context
  • No 7th: Lighter and more resolved than m7
  • Psychology: Nostalgic, bittersweet elegance

Scale Relationship

  • Derived from: Melodic minor scale (ascending)
  • Scale degrees: 1-b3-5-6 of melodic minor
  • Key insight: Am6 = F#m7b5 in first inversion
  • Equivalent: Half-diminished chord rearranged
  • Function: Stable minor tonic in jazz harmony

Classic swing-era turnaround using the minor sixth as a departure point, cycling through related harmony back to the dominant for resolution. Common in big band arrangements.

Practice Tips for Chord Progressions

Technique Focus
  • Practice the difference between m6 and m7 shapes on the same root
  • Focus on clean voicings and muting unused strings carefully
  • Use fingerpicking for bossa nova m6 comping patterns
  • Practice voice leading from m6 to its half-diminished equivalent
Musical Application
  • Use m6 as a jazz minor tonic instead of plain minor chords
  • Essential for authentic bossa nova and Brazilian jazz styles
  • Creates film noir atmosphere at slower tempos
  • Interchangeable with half-diminished chords for reharmonization

Famous Songs Using Minor Sixth Chords

Jazz & Bossa Nova Standards

  • "The Girl from Ipanema" - Antonio Carlos Jobim (Fm6 as tonic minor)
  • "Black Orpheus (Manha de Carnaval)" - Luiz Bonfa (Am6 throughout)
  • "My Funny Valentine" - Rodgers & Hart (Cm6 opening tonic)
  • "Round Midnight" - Thelonious Monk (Ebm6 jazz voicings)
  • "Blue in Green" - Miles Davis (Dm6 color chord)

Film Scores, Pop & Classic Recordings

  • "Cry Me a River" - Julie London (Cm6 opening vamp)
  • "Harlem Nocturne" - Earle Hagen (Gm6 noir theme)
  • "Pink Panther Theme" - Henry Mancini (Em6 motif)
  • "Fever" - Peggy Lee (Am6 hypnotic vamp)
  • "Chinatown" - Jerry Goldsmith (Fm6 film noir underscore)

Practice Exercises

Building Minor Sixth Skills

These exercises develop your ability to voice, hear, and apply minor sixth chords across musical contexts.

Exercise 1: Minor 6th vs Minor 7th Comparison

Pattern: Am6 - Am7 - Dm6 - Dm7 - Em6 - Em7

Alternate between minor sixth and minor seventh on the same root to train your ear to the subtle but important difference in color

The m6 sounds brighter and more resolved than the m7 - the raised 6th adds a melodic minor sweetness

Exercise 2: Bossa Nova Comping Pattern

Pattern: Am6 (2 bars) - Bm7b5 (1 bar) - E7 (1 bar)

Practice a classic bossa nova syncopated rhythm using the ii-V-i in A minor with m6 as the tonic chord

Keep the rhythm gentle and relaxed - bossa nova should feel effortless, with the thumb handling bass notes

Exercise 3: m6 and Half-Diminished Equivalents

Pattern: Am6 then F#m7b5, Dm6 then Bm7b5, Em6 then C#m7b5

Play each minor sixth chord, then revoice the same four notes as its enharmonic half-diminished equivalent to hear the inversion relationship

Same four notes, different bass note - understanding this unlocks advanced reharmonization and substitution possibilities

Advanced Minor Sixth Concepts

The m6 / Half-Diminished Relationship

  • Am6 (A-C-E-F#) = F#m7b5 (F#-A-C-E) rearranged:
  • Every m6 chord is a half-diminished chord in first inversion:
  • Dm6 (D-F-A-B) = Bm7b5 (B-D-F-A) rearranged:
  • Jazz players exploit this equivalence to find new voicings on familiar shapes:
  • This relationship is the key to understanding melodic minor harmony:

Minor Sixth in Melodic Minor Harmony

  • Melodic minor ascending: 1-2-b3-4-5-6-7
  • The m6 chord is the tonic (first degree) of melodic minor:
  • Jazz minor = melodic minor ascending used in both directions:
  • Contains both major 6th and major 7th over a minor triad:
  • Foundation for altered dominants, lydian dominant, and superlocrian scales:
