Workshop 103 — From Arrangement to Original Composition: Building a New Piece from Motif, Bass, Harmonic Function, Form, and Constraints
Workshop 102 ended with an important threshold:
If you can reduce an arrangement to its essential musical DNA and then rebuild it differently, you are already very close to composition.
Now we cross that threshold deliberately.
The goal is no longer:
“How can I arrange this existing tune?”
It becomes:
“How can I create a new tune whose melody, harmony, bass, rhythm, and form feel as though they belong to the same musical organism?”
This is where a lot of people get stuck.
They know:
- chords
- scales
- voicings
- motifs
- reharmonization
but when told:
“Write something original,”
they stare at the piano.
Why?
Because unlimited possibility is often harder than limitation.
So we will compose through constraints.
The central lesson is:
Original composition usually does not begin with infinite freedom. It begins with one strong limitation that generates consequences.
103.1The blank-page problemSuppose I tell you:103.2Now compareI tell you:103.3First principleComposition is often the art of choosing what will not be allowed.103.4Five useful starting pointsYou can begin a piece from:103.5Do not always start from chordsPianists often compose:103.6Level 1 — melody-first compositionChoose three notes:103.7Play the motifC-D-G.103.8Level 2 — exact repetitionBars 1–2:103.9Level 3 — change only final noteC-D-G.103.10Level 4 — sequenceMove motif:103.11Level 5 — contour preservationOriginal:103.12A motif does not need many notesBeethoven taught us that already.103.13Level 6 — rhythm-first compositionIgnore pitches.103.14Level 7 — build phrase from rhythm onlyFour bars:103.15Level 8 — add one pitchPlay entire phrase on:103.16Level 9 — add pitch contourUse:103.17Rhythm can generate melody rather than merely decorate itThis is one of the most important compositional habits.103.18Level 10 — bass-first compositionChoose bass:103.19First harmonize minimallyBass:103.20Level 11 — melody from top-line relationshipChoose top:103.21Level 12 — write melody against bass before chord symbolsThis is crucial.103.22Why?Because chord labels can cause habitual solutions.103.23Level 13 — harmonic-first compositionNow do the opposite intentionally.103.24Example top lineG → G → A♭ → B.103.25Level 14 — guide-tone generated melodyOver:103.26Add rhythmPerhaps:103.27Level 15 — harmony from inner lineChoose chromatic line:103.28Then expand itLater use:103.29A composition can have non-obvious thematic DNAThe listener may not consciously say:103.30Level 16 — texture-first compositionStart with:103.31Let texture generate formAfter four bars:103.32This is common in groove-based musicA composition may begin with:103.33Level 17 — groove-first compositionChoose:103.34A good groove composition often needs less harmonic motionBecause:103.35Level 18 — one-chord compositionUse only:103.36This is an excellent compositional examIf you need a new chord every two beats to create interest:103.37Level 19 — two-chord compositionUse:103.38Level 20 — three-chord limitUse:103.39Simple harmony is not simple compositionA powerful melody over I-IV-V can be much harder to write than:103.40Level 21 — melody constraint: five notes onlyIn C:103.41Pentatonic limitation helps melodyBecause there are fewer semitone conflicts.103.42Level 22 — four-note melodyUse only:103.43Level 23 — one repeated anchor noteUse G repeatedly.103.44Level 24 — one forbidden noteCompose in C major.103.45Level 25 — withheld 3rdUse C as tonal center.103.46Constraints can produce narrative automaticallyThe arrival of a previously forbidden note becomes:103.47Level 26 — register constraintFor first section:103.48Level 27 — rhythmic constraintMelody may use only:103.49Level 28 — rest constraintEvery 2-bar phrase must contain:103.50Silence is compositional materialYou are composing:103.51Level 29 — phrase-length constraintWrite three phrases:103.52Level 30 — 5-bar phraseWrite melody that genuinely needs:103.53Level 31 — asymmetrical periodQuestion:103.54Form need not be symmetricalBut asymmetry should feel:103.55Level 32 — sentence form conceptA useful classical-ish compositional model:103.56ExampleBars 1–2: motif A.103.57Level 33 — period conceptPhrase 1:103.58Question and answer need not mean V and I literallyThe question can end:103.59Level 34 — create question melodicallyEnd first phrase on:103.60Level 35 — create question rhythmicallyFirst phrase ends:103.61Level 36 — create question harmonicallyFirst:103.62Level 37 — create answer through contourQuestion rises.103.63Level 38 — create answer through registerQuestion stays middle.103.64Level 39 — write an 8-bar periodConstraints:103.65Level 40 — now reharmonize your own melodyThis is a major shift.103.66Original composition gives you both sides of the equationExisting tune:103.67Level 41 — melody/harmony negotiationSuppose melody ends F over desired Cmaj7.103.68Do not force your first melody against your first harmonyComposition is iterative.103.69Level 42 — bass negotiationSuppose bass line is beautiful but chord awkward.103.70Level 43 — motif negotiationIf motif does not survive harmonic change:103.71Iteration is normalFirst draft is not failure.103.72Level 44 — compose with a “complexity ceiling”For first draft:103.73Level 45 — second pass: extensionsOnly after composition works:103.74Level 46 — third pass: chromaticismNow allow:103.75Level 47 — fourth pass: textureNow decide:103.76This distinction is fundamentalComposition layer:103.77Level 48 — write a tune that survives bad arrangingCompose melody/harmony.103.78Level 49 — write an arrangement that upgrades simple compositionNow take same tune and make sophisticated solo piano version.103.79Level 50 — hookA hook is a memorable musical feature.103.80A hook does not need to be loudIt needs:103.81Level 51 — write three candidate hooksEach no more than:103.82Level 52 — hook variationState hook:103.83Level 53 — hook in bassWrite:103.84Level 54 — hook in harmonyExample:103.85Level 55 — hook as chord colorMaybe every A section features:103.86Level 56 — hook as silencePerhaps every main phrase contains:103.87Level 57 — create a B sectionA section has established:103.88Contrast optionsChange:103.89Level 58 — B section by harmonic contrastA: C major.103.90Level 59 — B section by rhythmic contrastHarmony remains C-ish.103.91Level 60 — B by texture onlySame key.103.92Level 61 — B by registerA: middle/high.103.93Level 62 — return ADo not copy automatically.103.94Level 63 — exact returnUseful if B was highly contrasting.103.95Level 64 — transformed returnUseful if development is important.103.96Level 65 — incomplete returnBring only first half of A.103.97Level 66 — false returnHint at A motif.103.98Level 67 — compose intro from future materialDo not write intro first.103.99Level 68 — compose ending from opening materialReturn intro motif.103.100Level 69 — write backward from endingChoose final sound first.103.101Backward composition is powerfulEspecially for:103.102Level 70 — choose climax noteBefore writing middle:103.103Level 71 — choose climax harmonyPerhaps:103.104Level 72 — choose climax rhythmMaybe first synchronized hit after long independence.103.105Level 73 — choose climax silencePossible:103.106Level 74 — climax by convergenceCombine:103.107Level 75 — anti-climaxSometimes deliberately avoid expected explosion.103.108Composition manages expectationEverything we studied about:103.109Level 76 — tension mapFor 32 bars write:103.110Level 77 — harmonic tension independent from dynamicsBar 24:103.111Level 78 — rhythmic tension mapStart:103.112Level 79 — register mapMiddle.103.113Level 80 — density map2 voices.103.114A composition can be designed as several overlapping curvesYou have:103.115Level 81 — one curve per draftDraft 1:103.116Level 82 — compose away from pianoImportant.103.117Level 83 — voice memo compositionSing a 4-bar idea into phone.103.118Level 84 — walk-and-composeTap pulse.103.119Level 85 — compose at piano but one finger onlyUse one RH finger.103.120Level 86 — compose harmony with shells onlyNo full voicings.103.121Level 87 — compose with no sustain pedalPedal can make weak progressions sound beautiful temporarily.103.122Level 88 — compose at whisper dynamicsSometimes playing loudly creates false excitement.103.123Level 89 — compose slowlyA fast groove can hide weak material.103.124Level 90 — compose without extensionsAgain:103.125The danger of “jazzing up” unfinished materialWhen a phrase feels weak, you may add:103.126Level 91 — melody revision testRemove accompaniment.103.127Level 92 — bass revision testPlay bass alone.103.128Level 93 — harmony revision testPlay chords without melody.103.129Level 94 — rhythm revision testTap entire melody.103.130Level 95 — form revision testReduce composition to:103.131Editing is compositionDeleting a section can be a larger compositional improvement than:103.132Level 96 — remove weakest four barsTake your 32-bar draft.103.133Level 97 — compressTurn 8-bar section into:103.134Level 98 — expandTake strongest 2-bar idea.103.135Level 99 — one-motif compositionWrite 32 bars.103.136Level 100 — two-motif compositionA:103.137Combining motifsPossible:103.138Level 101 — motif reconciliationIf A and B are contrasting:103.139Level 102 — harmonic motifUse recurring progression:103.140Level 103 — bass motif across sectionsBass cell:103.141Level 104 — rhythmic motif across style changeA section:103.142Level 105 — timbral/touch motifMaybe every important arrival uses:103.143Original composition can reuse all our arranging dimensionsYou can compose recurring:103.144Level 106 — write your “composition constitution”Before piece, define:103.145Level 107 — intentionally violate one ruleIf piece mostly modal:103.146Level 108 — revise the constitutionIf composition fights constraint too hard:103.147Level 109 — compose in an unfamiliar keyChoose:103.148Level 110 — compose in F♯ majorEven better for breaking visual habits.103.149Level 111 — compose in one hand position, then transposeWrite a motif in F♯.103.150Level 112 — compose minor by three versionsWrite melody centered A.103.151Level 113 — mode as compositional constraintD Dorian:103.152Level 114 — Lydian constraintC Lydian:103.153Level 115 — Mixolydian constraintC

exercise from “Mack the Knife”Do not use protected melody.103.166Conceptual exercise from “The Bare Necessities”Extract only abstract principles:103.167The deeper creativity lessonOriginality does not require:103.168The deeper melody lessonA melody becomes memorable less through:103.169The deeper harmony lessonHarmony becomes compositional when it contributes to:103.170The deeper bass lessonBass
