Workshop 70 — From Lead Sheet to Full Solo-Piano Arrangement: Melody First, Bass Second, Inner Voices Third, Chord Symbols Last
Workshop 69 ended with an important idea:
A complete solo-piano arrangement does not have to begin by choosing a chord symbol for every melody note.
That is exactly what we will do now.
This workshop is a synthesis of almost everything we have learned so far:
- melody hierarchy
- harmonic function
- bass-line design
- guide tones
- harmonic rhythm
- chord-melody voicing
- drop-2
- inner counterpoint
- reharmonization
- texture
- groove
- register
- form
But the order matters.
Today we deliberately use this workflow:
Melody → structural notes → bass → guide-tone lines → middle voices → harmonic labels → texture → reharmonization → form.
The chord symbol comes surprisingly late.
The central lesson is:
An arrangement should sound like several musical lines cooperating, not like a melody sitting on top of a spreadsheet of chord symbols.
70.1Start with melody aloneTake any legal lead sheet or melody you know.70.2Structural versus decorative melodySuppose a phrase contains:70.3Level 1 — mark the melody skeletonPlay only the structural notes.70.4Why skeleton mattersThe skeleton tells you where harmony has the strongest responsibility.70.5Level 2 — reduce melody rhythmTake the same phrase.70.6Do not permanently simplify the tuneThis is analysis.70.7Next: bass onlyDo not choose full chords yet.70.8Level 3 — roots onlyIf melody is in C major, begin with simple functional bass:70.9Test bass with melodyPlay:70.10Outer voices firstThe arrangement now consists of:70.11Level 4 — improve bass contourPerhaps root positions give:70.12Bass should be singablePlay LH alone.70.13Level 5 — use inversions deliberatelySuppose harmony can remain tonic while bass moves:70.14Do not confuse bass movement with harmonic movementBass can move while function stays tonic.70.15Level 6 — choose cadence bass carefullyPhrase endings matter disproportionately.70.16Now add one inner voiceDo not add a chord.70.17Level 7 — guide-tone lineSuppose bass suggests:70.18Play only three voicesLH bass.70.19Why three voices are enoughYou now have:70.20Level 8 — add second guide-tone lineIf needed, add another middle voice.70.21Now — and only now — ask for chord namesLook at the vertical combinations.70.22This reverses a common lead-sheet habitTypical approach:70.23Level 9 — melody determines extensionSuppose:70.24AnotherBass F.70.25This is much better than adding extensions randomlyDo not decorate a chord because:70.26Level 10 — preserve melody over multiple bassesSuppose melody holds:70.27But don't use all fourThis is the arranger's discipline.70.28Level 11 — plan harmonic rhythmNow decide:70.29Do not change harmony merely because melody movedYour bass may stay.70.30Level 12 — use color changes without functional changesSuppose root remains C.70.31Now choose textureSo far we have only designed pitches and lines.70.32Level 13 — texture follows phrase importanceA useful default:70.33Avoid “same texture forever”Even a beautiful voicing becomes dull if applied continuously.70.34Level 14 — build a texture mapFor an 8-bar phrase, decide:70.35This plan can precede exact voicingsYou do not need every note yet.70.36Level 15 — register mapAlso decide:70.37Register is formA melody repeated one octave higher automatically feels like development.70.38Level 16 — create an intro from the tune itselfInstead of generic:70.39Example methodTake three-note motif from melody.70.40Level 17 — create an ending from the phrase DNATake final melody fragment.70.41Level 18 — reharmonize only after baseline arrangement worksThis is critical.70.42Reharm should solve a problemGood reasons:70.43Level 19 — substitution by bass requirementSuppose bass wants:70.44Level 20 — substitution by inner-line requirementSuppose inner line wants:70.45Level 21 — substitution by melody colorSuppose melody holds:70.46Level 22 — substitution by harmonic rhythmPerhaps phrase is too static.70.47Level 23 — substitution by formFirst chorus: plain G7→C.70.48But preserve hierarchyDo not make early chorus more harmonically elaborate than climax unless that is intentional.70.49Level 24 — decide groove only after harmonic skeleton is understoodNow ask:70.50This is one of the course's deepest distinctionsSong70.51Level 25 — build the same skeleton in two stylesUse identical:70.52Version A — balladLH: roots/tenths.70.53Version B — swingLH: walking bass.70.54Level 26 — build a third version: bossaLH: root/fifth or syncopated bass.70.55This is the test of genuine arranging understandingIf your harmony only works in one texture:70.56Level 27 — build a fourth version: funkSimplify harmonic rhythm.70.57Structure is not sacred notationWe build a baseline to understand the tune.70.58Level 28 — arrange from four layersFor every phrase, think:70.59Add a fifth layer: rhythmNow ask:70.60Level 29 — staggered arrivalTarget chord: Fmaj9.70.61Level 30 — remove a layerAt any point, ask:70.62The solo-piano illusionOne pianist cannot literally be:70.63Level 31 — role rotationPhrase 1: melody + bass.70.64Level 32 — prioritize one layer per momentAt any moment, choose a foreground:70.65Level 33 — create an intensity graphFor a 32-bar arrangement, rate each phrase:70.66Intensity is multidimensionalHigher intensity can mean:70.67Level 34 — build climax through bass, not chordsKeep harmony simple.70.68Level 35 — build climax through melody textureBass unchanged.70.69Level 36 — build climax through harmonic rhythmTexture unchanged.70.70Level 37 — build climax through register onlyMove melody:70.71Level 38 — combine two intensity parametersFor example:70.72Avoid changing everything simultaneouslyIf:70.73Level 39 — design the returnAfter climax:70.74Level 40 — sparse ending after rich arrangementOne of the most powerful endings:70.75Full workflow — Pass 1Take a new tune.70.76Pass

exercise — 8-bar micro-arrangementTake any 8-bar melody.70.88Exercise — no chord symbolsArrange eight bars entirely by ear.70.89Exercise — symbols first versus lines firstMake two versions.70.90Exercise — three basses under one melodyTake four bars.70.91Exercise — three harmonic rhythmsSame phrase.70.92Exercise — three texturesSame exact harmony.70.93Ear Drill — outer voices onlyRecord melody + bass.70.94Ear Drill — add one guide toneNow add one middle line.70.95Ear Drill — excessive harmonyTake your arrangement.70.96Ear Drill — unnecessary chord changeRemove one passing chord.70.97Apply the workflow to “Happy Birthday”This is our perfect public-domain laboratory.70.98Apply the workflow to “Mack the Knife”Use your legal lead sheet/ear-learned melody.70.99Apply the workflow to “The Bare Necessities”Start with the tune's playful phrasing.70.100The major milestoneWe have spent many workshops learning:•Workshop 70 mini-test1. Why does this workflow delay chord symbols until relatively late?
