Workshop 63 — Triad Pairs and Upper-Structure Improvisation: Getting Modern Jazz Color Without Thinking in Seven-Note Scales
Workshop 62 taught us to step deliberately outside the harmony and return.
Now we take another advanced idea that initially sounds complicated but is actually a major mental simplification:
Instead of improvising from a seven-note scale, what if you think in two familiar triads?
This gives us triad pairs.
They are especially useful for:
- modal improvisation
- altered dominants
- Lydian sounds
- quartal/fusion language
- modern jazz phrasing
- upper-structure harmony
- avoiding scalar-sounding improvisation
The central lesson is:
A complicated scale can become musically easier when you reorganize it into two simple melodic objects your hands and ears already understand.
63.1Start with something completely familiarC major triad:63.2Play each triad separatelyRH:63.3AlternateC-E-G63.4Why omit one scale degree?A triad-pair system often uses two non-overlapping triads.63.5Level 1 — C major + D minor over C majorLH:63.6But there is a problemF = 11.63.7This immediately connects to Workshop 60Over a C pedal:63.8Level 2 — make phrases, not triad drillsDo not play:63.9RuleTriads are your source shapes.63.10Level 3 — change directionTry:63.11Another patternE-C-G63.12Why inversions matter melodicallyIf you only know root-position triads, triad-pair improvisation sounds like:63.13Level 4 — nearest-note connectionStart:63.14Level 5 — rhythmic motif across triadsChoose rhythm:63.15Level 6 — avoid starting every phrase on a rootBegin on:63.16Triad pair #2 — C major + D majorNow change only:63.17This is a beautiful Lydian triad pairC major + D major.63.18Play over C pedalLH: C-G.63.19CompareC + D minor:63.20Level 7 — C Lydian improvisation from two triadsUse only:63.21Why this often sounds better than “play C Lydian”Because the instruction:63.22Level 8 — alternate triads rapidlyPlay:63.23But leave restsDo not turn this into another continuous six-note stream.63.24Triad pair #3 — D minor + E♭ major over C minorNow return to C minor/Dorian territory.63.25Functions over CD minor: 9,11,13.63.26Notice something importantThe tonic root C is absent from both RH triads.63.27Level 9 — C-Dorian modal soloLH: C ostinato.63.28This forces you into color tonesYour RH automatically emphasizes:63.29Level 10 — Dorian versus Aeolian triad pairFor C Aeolian:63.30CompareC Dorian pair: Dm + E♭.63.31Triad pair #4 — dominant sus environmentOver C7sus / C pedal:63.32What makes a useful pair?Often:63.33Triad pair #5 — altered dominantNow the powerful one.63.34A♭ minor triadA♭ C♭ E♭.63.35B♭ minor triadB♭ D♭ F.63.36This is extremely usefulLH: G.63.37PlayA♭-B-E♭63.38Level 11 — altered dominant without thinking “altered scale”Instead of mentally spelling:63.39Why it sounds angularBecause each triad has thirds.63.40Level 12 — resolve each triad differentlyA♭m over G:63.41This connects directly to Workshop 61We said:63.42Level 13 — don't always play complete triadsOver G7alt:63.43Triad pair #6 — Lydian dominantTake F7♯11.63.44This introduces a useful distinctionSometimes you need:63.45Upper-structure triad notationConceptually:63.46Level 14 — dominant upper structureLH: F-A-E♭.63.47This is why upper structures are so valuable on pianoA terrifying-looking chord symbol may reduce to:63.48Level 15 — another dominant upper structureG7 altered.63.49Important anti-patternDo not learn:63.50Level 16 — major triad one whole step above major tonicC major context:63.51Compare with D minorOver C:63.52Level 17 — upper triad changes while shell staysLH:63.53Level 18 — improvisation by alternating upper structuresOver C Lydian:63.54Build a table mentallyC + D major.63.55Level 19 — rhythmic organizationTake C Lydian pair.63.56Try 3+3+2C-major fragment: 3 notes.63.57Level 20 — 3-note cells over 4/4Repeat one three-note triad inversion continuously.63.58But don't lose the barWorkshop 48 rules still apply.63.59Level 21 — triad pairs with articulation contrastTriad A: legato.63.60Level 22 — register contrastC-major triad fragment:63.61Level 23 — one triad stable, other changesOver C pedal:63.62Level 24 — triad pair into functional cadenceC Dorian vamp:63.63Hear the progression of thoughtDm + E♭.63.64Level 25 — do not use pair constantlyIf every phrase is built from alternating triads:63.65Level 26 — triad-pair sequenceTake inversion:63.66Level 27 — contrary-direction pairFirst triad ascends:63.67Level 28 — alternate two-note fragmentsFrom C major:63.68Level 29 — interval extractionC+D major triad pair contains many useful intervals.63.69Level 30 — chord voicing from triad pairInstead of improvising, stack parts of both triads.63.70Upper structure plus melodySuppose melody note is A over C.63.71Level 31 — harmonizing melody by upper triadSuppose melody note:63.72AnotherMelody:63.73Level 32 — slash-chord ear drillPlay bass C.63.74Level 33 — reharmonization by upper triadKeep melody note constant.63.75Level 34 — avoid low triadsUpper structures belong in the upper register for a reason.63.76Level 35 — shell + upper triadOne of the most valuable practical piano formulas:63.77Another formulaG7alt:63.78Level 36 — three layersLH: root.63.79Level 37 — remove the shellNow play:63.80That's a major ruleGuide tones tell us what the chord is doing. Upper structures tell us what color it has.63.81Level 38 — altered pair with resolutionG bass.63.82Don't resolve complexity into complexityIf dominant is:63.83Practice Loop A — C + D major over CFive minutes.63.84Practice Loop B — Dm + E♭ over CC pedal.63.85Practice Loop C — A♭m + B♭m over GG bass.63.86Practice Loop D — shell + upper triadF7♯11:63.87Practice Loop E — same pair, rhythm changesC+D major.63.88Practice Loop F — one triad per phrasePhrase 1: only C-major fragments.63.89Practice Loop G — pair→ordinary melodyOne bar triad-pair line.63.90Ear Drill — D minor or D major over C?Play:63.91Ear Drill — guide tone or color?Over F7, remove A/E♭ and play only G-major triad.63.92Ear Drill — Dorian pairAgainst C bass:63.93Ear Drill — altered pairG bass.63.94Mini-composition exerciseWrite 24 bars with three harmonic environments.63.95Apply it to “Happy Birthday”Use the melody as the top voice.63.96Apply it to “Mack the Knife”Keep walking swing conventional for the melody chorus.63.97Apply it to “The Bare Necessities”This is especially fun in the fusion/funk version.63.98The deeper cognitive lessonEarly in the course, we reduced music to:63.99This mirrors rhythmic chunkingRemember:•Workshop 63 mini-test1.
