Workshop 33 — “Dolphin Dance”: Ambiguous Tonal Centers, Lydian Colors, Slash Chords, and Harmony That Changes Its Meaning While You Listen
This workshop combines several things we’ve learned separately:
- modal color
- slash chords
- pedals
- upper structures
- non-functional movement
- functional cadences
- ambiguous tonal centers
- guide-tone voice leading
The new challenge is:
What if a chord sounds stable at first, then later reveals that it was actually part of a larger directional progression?
That is a very common feature of sophisticated jazz harmony.
The central lesson is:
A chord’s meaning is not always contained inside the chord itself; sometimes you only understand it after hearing what comes next.
33.1Harmony can be retrospectively understoodSuppose you hear:33.2Start with a simple examplePlay:33.3AnotherPlay:33.4Level 1 — delay analysisWhen you hear an unfamiliar chord:33.5The danger of instant Roman numeralsIf you immediately force every chord into the current key, you may get an extremely complicated analysis.33.6Lydian major color reviewIn C:33.7Practical voicingLH: C.33.8Level 2 — Lydian as local color, not global keySuppose one chord is:33.9Modes can describe chords locallySometimes “Lydian” is best understood as:33.10Level 3 — major chord with ♯11Take:33.11Why natural 11 is often awkward over majorD♭ major has:33.12Level 4 — melody note creates Lydian colorIf melody is G over D♭maj7:33.13Top-down voicingMelody G.33.14Level 5 — local major-color shiftsTry:33.15Do not ask for classical modulation yetJust hear:33.16Level 6 — common-tone glueTake:33.17Example voice-leadingCmaj7: E-G-B33.18Level 7 — bass leap versus inner smoothnessThis is a recurring advanced-jazz effect:33.19Level 8 — slash chord reinterpretationSuppose RH is:33.20This is useful in fluid harmonyYou can preserve an upper shape across a bass change.33.21Level 9 — pivot sonorityA pivot is something that can belong meaningfully to more than one harmonic environment.33.22Simple pivot exampleAm7 belongs to:33.23Modern pivot ideaAn upper triad may stay while bass changes.33.24Level 10 — same note, new identityHold:33.25The note does not know its functionFunction is contextual.33.26Level 11 — melodic anchor through harmonic ambiguityTake one melody note, perhaps G.33.27ExampleTop G.33.28Level 12 — harmonic rhythm as clueIf one strange chord lasts:33.29Structural durationLong chords usually deserve:33.30Level 13 — arrival zones versus transition zonesMark a passage as:33.31Example conceptArrival: Cmaj7♯11.33.32Level 14 — melodic targets during transitionIf next arrival is A♭maj7:33.33Level 15 — guide-tone corridorImagine that the chords are changing rapidly, but one inner voice moves:33.34Play the line aloneE-E♭-D-D♭-C.33.35Level 16 — bass corridorSame idea in bass:33.36Level 17 — two corridors at onceAdvanced:33.37Chord symbols come afterwardTake the two lines.33.38Level 18 — altered dominant as bridgeSuppose you need to move toward a remote major arrival.33.39Use certainty strategicallyIf several bars are harmonically ambiguous:33.40Level 19 — sus before dominantUse:33.41Level 20 — do not resolve the susAlternative:33.42Level 21 — diminished bridgeA diminished chord can connect distant harmonies through semitone voice-leading.33.43But do not use diminished as decoration automaticallyAsk:33.44Level 22 — upper-structure triad approachSuppose bass is G dominant-ish.33.45Add the guide tones carefullyG dominant needs:33.46Level 23 — upper structure versus functional shellThink in layers:33.47Shell + colorThis is a universal voicing formula:33.48Level 24 — color omissionIf melody is already A♭ over G7:33.49Level 25 — rootless ambiguityPlay RH:33.50Level 26 — remove bass againListen to the RH cluster alone.33.51Level 27 — improvisation: destination-firstFor an 8-bar harmonically fluid passage:33.52Level 28 — one motif through ambiguous harmonyUse a three-note motif.33.53Level 29 — common-tone soloPick a pitch that works through multiple chords.33.54This is especially sophisticatedYou are not merely “playing the changes.”33.55Level 30 — register hierarchyUse:33.56Level 31 — avoid low extensionsEspecially:33.57Level 32 — pedal as resetIf a complex passage becomes too busy:33.58Level 33 — reharmonization restraintA tune with already fluid harmony does not need constant extra substitutions.33.59Level 34 — simplify to triads over bassTake a complicated chord sequence.33.60Example conceptual reductionInstead of:33.61Level 35 — sing upper triadLH plays bass.33.62Level 36 — sing bass against RH chordRH holds a triad.33.63Level 37 — improvise over one upper structure with changing bassRH melodic vocabulary from:33.64Level 38 — improvise over one bass with changing upper structuresBass C remains.33.65These are complementary skillsreinterpretation.33.66Level 39 — phrase architectureFor a 16-bar section:33.67Harmony type can create formYou do not always need:33.68Level 40 — introUse one stable upper triad.33.69Example conceptRH: C major triad.33.70Level 41 — endingOption 1:33.71Open major endingSuppose tonic is C.33.72Warmer endingC6/9:33.73Practice loop A — Lydian major colorsPlay:33.74Practice loop B — sustained note reinterpretationHold G.33.75Practice loop C — same RH triadRH C major.33.76Practice loop D — guide-tone corridorChoose a chromatic line:33.77Practice loop E — sus to functionE♭7sus33.78Improvisation challenge 1 — three destinationsTake eight bars of changing harmony.33.79Challenge 2 — one common noteChoose G.33.80Challenge 3 — no scale runsUse only:33.81Challenge 4 — slash-chord melodyChoose a slash chord such as D♭/E♭.33.82Challenge 5 — ambiguity to certaintyCreate 8 bars:33.83Ear drill — Lydian ♯11Play major chord.33.84Ear drill — chord meaning changes after contextPlay one major chord.33.85Ear drill — slash identityPlay upper triad first.33.86Ear drill — arrival zonePlay several ambiguous chords.33.87Mini-composition exerciseWrite 12 bars with:33.88The major conceptual upgradeEarlier, we often asked:33.89Harmony is temporalA chord is not just a stack of frequencies.33.90Connection to arranging simple melodiesTake any simple tune.33.91And notice how little technique it requiresOne sustained melody note.33.92Workshop 33
