Workshop 69 — Chord-Melody Architecture: Four-Way Close, Drop-2, Block Chords, Melody on Top, Inner-Voice Logic, and Turning a Single Line into a Piano “Section”
Workshop 68 taught us that harmony has a rhythm: when chords change can matter as much as which chords they are.
Now we tackle a major piano-arranging skill that has appeared repeatedly in our repertoire work but deserves its own laboratory:
How do you turn one melody note into a convincing chord-melody texture without merely stacking random chord tones underneath it?
This is where we study:
- melody-on-top voicing
- four-way close
- drop-2
- block chords
- locked-hands concepts
- harmonizing passing notes
- approach diminished chords
- inner-voice lines
- register management
- when not to harmonize every note
The central lesson is:
Chord melody is not “play the chord under every melody note.” It is voice leading arranged around a protected top voice.
69.1Melody has absolute priorityTake a melody note:69.2First exercise: melody balanceRH:69.3A practical touch hierarchyThink:69.4Level 1 — melody + one supporting toneMelody G over C.69.5Which support tone?G over C can pair with:69.6Level 2 — melody + shellSuppose harmony is G7 and melody is:69.7This is the first practical formularoot or bass.69.8Level 3 — melody as extensionSuppose G7 melody note is:69.9AnotherG7 melody:69.10This is a huge ruleWhen melody is:69.11Level 4 — four-way closeNow we introduce classic block-chord logic.69.12Four-way close conceptMelody:69.13Why “four-way”?Four voices total.69.14Level 5 — harmonize a scale in close positionUse C major.69.15Why mechanical harmonization is usefulIt teaches:69.16The problem with harmonizing every scale note literallySuppose melody has passing note:69.17Level 6 — keep harmony, adapt voicingHarmony remains C6.69.18Example conceptOver C6:69.19The distinctionnew function/root.69.20Level 7 — parallel block movementTake a simple melody fragment:69.21Why it sounds orchestralA horn section often moves:69.22Level 8 — locked-hands conceptClassic locked-hands texture often doubles melody:69.23Example conceptMelody G.69.24Do not use locked hands continuously at firstIt can sound:69.25Level 9 — single note → sixths → octaves → blocksTake one phrase.69.26This is perfect for repeated chorusesChorus 1: single line.69.27Level 10 — drop-2Now the important voicing technique.69.28ExampleSuppose close Cmaj7 voicing is:69.29Why drop-2 mattersClose position can sound:69.30Think spatiallyClose position:69.31Level 11 — physical drop-2 drillTake:69.32Do not calculate foreverAt first:69.33Level 12 — melody on top of drop-2Take melody:69.34Chord-melody hierarchyWhen applying drop-2:69.35Level 13 — drop-2 through ii–V–IC major:69.36This is the sweet spotGuide-tone top line:69.37Level 14 — melody not chord toneSuppose G7 melody is:69.38Level 15 — melody is ♯11F7 harmony.69.39The melody itself can tell you the scale/color systemIf melody is B over F7:69.40Level 16 — avoid unnecessary 5thsSuppose chord is:69.41Priority orderWhen voicing under melody:69.42Level 17 — inner voice as counter-melodySuppose top melody:69.43Two voices firstTop: melody.69.44Level 18 — descending inner lineTop melody repeats:69.45Level 19 — contrary inner motionMelody rises:69.46Level 20 — don't harmonize short pickup notesSuppose melody has:69.47This is one of the best texture rulesHarmonize structural notes more heavily than connective notes.69.48Level 21 — selective block chordsUse blocks only on:69.49CompareVersion A: every melody note block-harmonized.69.50Level 22 — approach-note harmonizationNow suppose melody approaches a chord tone chromatically.69.51Example conceptTarget chord:69.52Diminished passing harmonizationOne classic principle:69.53Level 23 — C6 / diminished alternation conceptC6 notes:69.54Practical drillMelody:69.55Level 24 — chromatic planing insteadInstead of diminished logic:69.56So we now have two approach languagesdiminished passing harmony.69.57Level 25 — diatonic passing harmonizationNot every passing melody note needs diminished harmony.69.58Level 26 — dominant block chordsOver G7 area, build melody blocks around:69.59This is a huge practical insightInstead of memorizing many giant G7 chord symbols:69.60Level 27 — dominant color ladderG bass.69.61Level 28 — block chord into tonic simplificationPlay dense altered G7 block.69.62Level 29 — melody doubling at octaveFor climactic note:69.63Level 30 — sixth harmonizationA lighter alternative.69.64Compare texturestransparent.69.65Level 31 — register disciplineDo not put dense block chords too low.69.66Low-interval limitsLow register likes:69.67Level 32 — spread chord melodyMelody high.69.68Chord melody is not synonymous with block chordsA ballad chord-melody arrangement may be:69.69Level 33 — harmonize only phrase endingsTake an 8-bar melody.69.70Level 34 — harmonize only repeated notesIf melody repeats one pitch:69.71Level 35 — keep top melody fixed, move block beneathHigh G.69.72Level 36 — chord melody with walking bassHarder.69.73Level 37 — chord melody with strideStride LH is busy.69.74Level 38 — chord melody in bossaLH bass + syncopation.69.75Level 39 — chord melody in funkUsually:69.76Level 40 — chord melody in 3/4Melody note may be harmonized on:69.77Practice Loop A — melody top balanceTake five triads.69.78Practice Loop B — shells under melodyChoose random G7 melody notes:69.79Practice Loop C — close vs drop-2Choose one four-note voicing.69.80Practice Loop D — selective harmonizationTake a simple 8-bar melody.69.81Practice Loop E — one inner lineMelody fixed.69.82Practice Loop F — diminished approachChoose a target block chord.69.83Practice Loop G — texture ladderSame phrase:69.84Improvisation Challenge 1 — chord melody without rootLH silent.69.85Challenge 2 — melody only + block punctuationFour bars.69.86Challenge 3 — one block shape transformedTake a comfortable drop-2 shape.69.87Challenge 4 — guide-tone top lineUse:69.88Challenge 5 — dominant color melodyG7 pedal.69.89Challenge 6 — density arc16 bars:69.90Ear Drill — close or drop-2?Play same harmony in both forms.69.91Ear Drill — melody extensionOver G7, hear top:69.92Ear Drill — new chord or new voicing?Keep C bass/function.69.93Ear Drill — structural versus passing melody notePlay:69.94Mini-composition exerciseWrite a 32-bar solo-piano chord-melody study.69.95Apply it to “Happy Birthday”This public-domain melody is an ideal laboratory.69.96Apply it to “Mack the Knife”This is where the requested song laboratory becomes more sophisticated.69.97Apply it to “The Bare Necessities”Use blocks differently.69.98The deeper arranging lessonWe now have four different things that people casually call “changing the harmony”:69.99The deeper piano lessonYour hands should gradually stop thinking:69.100Where this leadsOnce drop-2, melody-top voice leading, guide tones, and texture control are fluent, we can do something very powerful:•Workshop 69 mini-test1.
