Workshop 105 — Composing the Harmonic World Under an Original Melody: Making Chords Feel Inevitable Instead of Merely Interesting

Workshop 104 was about writing stronger original melodies.

Now we ask the next compositional question:

Once you have a melody that works, how do you create harmony underneath it that feels like it belongs to that melody—rather than like a bag of chords chosen afterward?

This is where many otherwise good compositions become weaker.

The melody may be memorable.

The chords may individually sound beautiful.

But together they may feel:

The central lesson is:

Good harmony underneath an original melody is not the accumulation of attractive chords. It is the creation of a tonal environment in which the melody’s important notes, phrase destinations, tensions, and returns feel increasingly inevitable.

105.1First principleDo not begin with:42 words105.2Melody note does not determine chordSuppose melody note:32 words105.3Phrase context narrows choicesIf G is:44 words105.4Level 1 — harmonize phrase destinations firstTake an 8-bar original melody.35 words105.5Why?Because those are:15 words105.6ExampleSuppose melody in C major.35 words105.7Now work backwardWhat prepares G7?15 words105.8Destination-first harmonyThis is exactly the same principle we used in:17 words105.9Level 2 — use only three functionsFor first draft, restrict yourself to:25 words105.10Do not write chord symbols yet if that distracts youYou can annotate:17 words105.11Level 3 — one functional change per phrase segmentAvoid changing harmony every melody note.25 words105.12Harmonic patience matters in compositionA melody can use:23 words105.13Level 4 — tonic as a region, not one chordIn C major, tonic region can include:28 words105.14Level 5 — write two bars that stay “home”Use melody over:17 words105.15Level 6 — predominant as preparationUse:21 words105.16Level 7 — dominant as energyUse:13 words105.17The exact chord is secondary to directional roleThis is a major compositional discipline.6 words105.18Level 8 — write functional skeleton before colorExample:32 words105.19Level 9 — melody-note compatibility passNow check structural melody notes.24 words105.20Possible responseKeep Am and embrace F as:24 words105.21Level 10 — ask whether tension is structuralIf unusual melody/chord combination occurs on:22 words105.22Structural dissonance needs purposeA long F over C major triad may sound like:23 words105.23Level 11 — melody as extensionSuppose chord:20 words105.24Level 12 — melody as 7thChord:19 words105.25Level 13 — melody as 3rdChord:15 words105.26Composition and arrangement interact hereIf melody supplies important chord tone:19 words105.27Level 14 — bass-first reharmonization of your own melodyTake your melody.23 words105.28Why this is powerfulBass supplies:17 words105.29ExampleBass:16 words105.30Level 15 — melody+bass testBefore adding middle notes:27 words105.31Outer voices firstThis remains one of the strongest rules in the entire course.11 words105.32Level 16 — contrary motionMelody rises.15 words105.33Level 17 — parallel motionMelody and bass move together.14 words105.34Level 18 — oblique motionMelody holds.19 words105.35Level 19 — common-tone harmony under sustained melodyMelody:25 words105.36Level 20 — harmony from an inner lineInstead of bass:20 words105.37Example possibilitiesE over C.21 words105.38Level 21 — one-note motion ruleHold most voicing.23 words105.39Harmony can evolve by transformation, not replacementA mature progression does not always sound like:23 words105.40Level 22 — voice-leading-first progressionChoose four voices.24 words105.41ExampleTop four notes:20 words105.42Level 23 — chord symbol after soundPlay/hear voice-leading.18 words105.43Level 24 — root motion architectureRoot motion has character.24 words105.44Circle motionD→G→C.9 words105.45Stepwise rootsC→Dm→Em→F.12 words105.46Chromatic rootsC→C♯°→Dm.8 words105.47Third-related rootsC→E→A♭ etc.15 words105.48Pedal rootsC under changing upper harmony.10 words105.49Level 25 — root motion profileFor 8 bars choose:20 words105.50Harmony has rhythm tooDo not only choose:14 words105.51Level 26 — one chord per barWrite 8 bars.8 words105.52Level 27 — accelerate toward cadenceExample:32 words105.53Level 28 — decelerate into arrivalFast changes.14 words105.54Level 29 — dominant prolongationInstead of rapidly changing chords near cadence:20 words105.55This creates tension without root clutterExtremely useful.2 words105.56Level 30 — tonic prolongationCmaj715 words105.57Level 31 — color rhythm versus function rhythmWrite a phrase with:16 words105.58Level 32 — do the oppositeFour functional changes.14 words105.59Level 33 — harmonic density and melodic densityBusy melody:18 words105.60ExampleMelody holds G for two bars.23 words105.61Harmony should not compete with melodic information rateThe composition has a shared complexity budget.7 words105.62Level 34 — cadence vocabulary for original compositionYou should be able to choose cadence by emotional role.33 words105.63Level 35 — write same phrase with five cadencesKeep melody ending constant.19 words105.64Level 36 — melody ending determines cadence optionsMelody ending:19 words105.65Level 37 — cadence-generated melodyReverse.12 words105.66Harmony and melody can co-compose each otherThis is more mature than thinking one must always come first.11 words105.67Level 38 — use one signature harmonic eventFor your original piece choose:21 words105.68Do not turn signature into wallpaperIf special event happens every four bars:16 words105.69Level 39 — harmonic motifA progression itself can function like melodic motif.18 words105.70Level 40 — voice-leading motifMaybe recurring inner movement:16 words105.71Level 41 — cadence motifEvery section closes with:15 words105.72Level 42 — harmonic rhythm motifPerhaps important phrases always use:15 words105.73Level 43 — harmonic restraint in A sectionKeep A:13 words105.74Level 44 — chromatic B sectionIntroduce:18 words105.75Contrast does not require modulationYou can change harmonic language without changing tonic.19 words105.76Level 45 — functional A, modal BA: C-Am-Dm-G.14 words105.77Level 46 — major A, parallel-minor BA: C major.16 words105.78Level 47 — relative-minor BA: C major.16 words105.79Level 48 — remote B sectionMove to:23 words105.80Modulation should solve a form problemGood reasons:28 words105.81Level 49 — local tonicizationYou don't need full modulation.18 words105.82Secondary dominants as illuminationA chord becomes more important because it receives its own dominant.19 words105.83Level 50 — tonicize the melodic climaxSuppose climax note:19 words105.84Level 51 — tonicize structural predominantWant Dm to feel significant.13 words105.85Level 52 — dominant chainA7→D7→G7→C.11 words105.86Level 53 — bass line inside dominant chainGuide voice:19 words105.87Level 54 — borrowed harmonyIn C:18 words105.88Borrowed iv is especially effective because of voice leadingF major:20 words105.89Level 55 — compose borrowed harmony from lineWrite:16 words105.90Level 56 — ♭VI in minor/major mixtureIn C:18 words105.91Level 57 — ♭VIIB♭ in C.16 words105.92Level

chromatic chord through a compelling line or destination, it is much more likely to sound composed rather than…25 words105.96Level 61 — harmonic surpriseFirst establish expectation.20 words105.97Level 62 — delayed tonicG7.22 words105.98Level 63 — false cadenceApproach tonic strongly.15 words105.99Level 64 — final cadence simpler than earlier onesInteresting possibility.15 words105.100Complexity does not have to increase until final chordSometimes final simplicity is the point.6 words105.101Level 65 — harmonic tension curveFor 16 bars, write:30 words105.102Level 66 — tension through dominant durationHigher tension does not necessarily require stranger chord.15 words105.103Level 67 — tension through root distanceC→D♭ creates immediate foreignness.13 words105.104Level 68 — tension through altered tonesG710 words105.105Level 69 — tension through registerSame chord.14 words105.106Level 70 — tension through densityG7 shell:16 words105.107Level 71 — harmonic releaseAfter rich dominant:19

words105.111Level 75 — melody arrives before harmonyMelody hits C.17 words105.112Level 76 — compose arrival orderAt important cadence, write:22 words105.113Level 77 — write harmony that reveals mode graduallyStart C/G open.16 words105.114Level 78 — major/minor ambiguityUse:17 words105.115Level 79 — change identity laterFirst reveal:13 words105.116Level 80 — sus as delayed identityUse:16
