Chord Melody

Chord melody is the art of playing melody and harmony simultaneously — no accompanist required. A chord melody arrangement carries the tune in the top voice while inner voices and bass provide the harmony. It's the solo guitar tradition: Joe Pass, Ted Greene, Lenny Breau, Johnny Smith. On piano it's the stride tradition extended into modern harmony. The goal is to sound like a complete group: melody, harmony, and bass — all from one instrument.

The Core Principle

The melody is always the highest note. Everything beneath it — the chord voicing — supports and colours that melody. The starting challenge is finding voicings where the melody note sits on top, which means working backwards from the melody note rather than forwards from the chord shape. Each melody note tells you where the top of the voicing must be; you build down from there.

Melody note = E (major 3rd of Cmaj7 chord)
Required: a Cmaj7 voicing with E on top

Options:
  E G B C  (3rd, 5th, 7th, root — close position, E on top)
  E G C B  (3rd, 5th, root, 7th — re-ordered)
  E C G B  (drop voicing variant)

Any voicing where E is the highest pitch works.
Avoid voicings where another note ends up higher than E.

Building a Chord Melody Arrangement

Get the melody solidly in your ear. Sing it. Know where every melody note falls in the bar.
Identify the chord for each melody note (from the lead sheet or chord chart).
Find a voicing of that chord with the melody note on top — work backwards from the melody.
Add a bass note on the lowest available string.
Fill in inner voices between bass and melody — 2 to 4 total notes is typical.
Not every melody note needs a full chord. Let some notes ring; walk the bass between chord changes.

Common Voicing Strategies

Strategy	Description	Best for
Drop 2	Take a 4-note close position chord and drop the 2nd-highest note down an octave	Spreads voicing into playable range; keeps melody on top
Shell voicings	Root + 3rd (or 7th) + melody note only — 3 notes total	Fast-moving melodies; clarity over density
Rootless voicings	Omit root; use 3rd, 7th, and extensions + melody on top	Ensemble context with bassist; richer colour
Inversions	Put 3rd or 5th in bass (slash chord) instead of root	Smooth bass lines; melodies that aren't on the root

Voice Leading

Voice leading — how individual voices move from chord to chord — is what makes a chord melody arrangement sound musical rather than mechanical. The principle: each voice should move to the nearest available note in the next chord:

Moving from Dm7 to G7 (inner voices):
  Dm7: D  F  A  C   (root, 3rd, 5th, 7th)
  G7:  G  B  D  F   (root, 3rd, 5th, 7th)

Inner voice mapping:
  F → F   (common tone — stays on F, which is G7's minor 7th)
  A → B   (up a whole step — smooth)
  C → B   (down a half step — even smoother)

Bass: D → G  (down a fifth — standard root motion)

Reharmonisation

Chord melody gives enormous freedom to reharmonise — to substitute different chords under a melody as long as the melody note works over the new harmony. The only constraint: the melody note must be a chord tone or usable extension of the substitute chord:

Original: Cm7 in bar 1, melody note = E♭ (♭3 of C minor)

Substitutes where E♭ works:
  E♭maj7     (E♭ = root — major sound)
  A♭maj7     (E♭ = 5th — subdominant feel)
  Fm7        (E♭ = ♭7 — minor colour)
  D♭7        (E♭ = 9th — tritone sub dominant colour)
  G♭maj7     (E♭ = #11 / enharmonic D# — Lydian sound)

Each gives a completely different harmonic colour under the same melody note.

Where to Start

Start with tunes that have long sustained melody notes — "Misty," "Round Midnight," "Autumn Leaves," "Summertime." Sustained melody notes give you time to place full voicings. Fast bebop heads are much harder because the melody moves too fast to harmonise every note. Beginners should also consider starting with simple folk melodies before moving to jazz standards.

Essential Listening

Artist	Recording	What to study
Joe Pass	Virtuoso (1973)	Walking bass under sustained melody; harmonic freedom
Ted Greene	YouTube recordings	Inner voice movement; dense extended voicings
Lenny Breau	Five O'Clock Bells	Impressionistic reharmonisation; harmonics with chord melody
Johnny Smith	Moonlight in Vermont	Clean, lyrical melody on top; bebop-era vocabulary
Bill Evans (piano)	Waltz for Debby	Melody as top voice; rootless left-hand voicings
