Workshop 34 — “Invitation”: Minor-Key Gravity, Descending Bass, Dominant Chains, and Hearing Long Harmonic Sentences
After the floating harmony of “Naima” and “Dolphin Dance,” this workshop brings strong harmonic gravity back—but in a less predictable way than a simple ii–V–i.
The challenge is:
Can you hear a long chromatic progression as one directional sentence instead of a succession of mysterious chords?
“Invitation” is especially useful for studying:
- minor tonic as a structural home
- chromatic descending bass
- dominants that temporarily point away from home
- local tonicization
- deceptive or delayed resolutions
- half-diminished chords
- diminished connectors
- long-range voice leading
- improvising toward destinations several chords away
We’ll use C minor as our conceptual laboratory rather than reproduce a full chart.
The central lesson is:
A complicated progression becomes much easier when you hear the bass line and know which arrivals actually matter.
34.1Begin with the destinationC minor:34.2Establish C minor stronglyPlay:34.3Now delay that resolutionSuppose instead of immediately resolving G7 to Cm, the harmony moves elsewhere.34.4Functional harmony is about promisesA dominant effectively promises something.34.5Level 1 — dominant predictionPlay:34.6Then practice “broken promises”Play:34.7Deceptive motion is contextualThere is no single universal “deceptive chord.”34.8Level 2 — descending bassPlay bass only:34.9Why this bass is so powerfulIt combines:34.10Harmonize minimallyTry:34.11First four bass notesC → B → B♭ → A.34.12Add ♭6A♭.34.13Transpose itA minor:34.14Level 3 — top note stays fixedHold melody:34.15Then add only one inner voiceFor example:34.16Level 4 — inner line and bass line disagreeBass descends:34.17Chords emerge from counterpointThis is an important mature-theory point.34.18Level 5 — half-diminished chord as directional deviceIn minor keys, m7♭5 often tells you:34.19If the global key is C minorG minor is not the final tonic.34.20This is local tonicizationA chord can temporarily feel like I/i without becoming the ultimate home of the piece.34.21Level 6 — weight the arrivals differentlySuppose you have:34.22Ways to give structural tonic more weightUse:34.23Level 7 — minor destinations mapPractice these:34.24Then connect destinationsAm → Gm → Fm → Cm, conceptually.34.25Level 8 — dominant chainTry:34.26But note the tonic qualityE7 normally predicts A.34.27This is importantG7 contains:34.28PlayG7 → Cmaj7.34.29Level 9 — use dominant alterations to foreshadow minorInto C minor:34.30G7♭13 → CmHold E♭.34.31Level 10 — dominant without rootG7♭9:34.32Compare bass pathsG → C.34.33Level 11 — three roads homePlay:34.34The theoretical commonalityG7 and D♭7 share the tritone:34.35Level 12 — chromatic dominant descentTry:34.36The first cadenceD → G → C.34.37Level 13 — hear bass shape before functionWhen you see a progression like:34.38Level 14 — diminished passing connectorSuppose bass:34.39AnotherF → F♯ → G:34.40Do not insert diminished chords randomlyA diminished chord is most convincing when it:34.41Level 15 — melody-note reinterpretationHold melody:34.42This is excellent for “Invitation”-type harmonyThe melody can remain lyrical while harmony shifts underneath.34.43Level 16 — long melody note, active bassHold E♭ for four bars.34.44Level 17 — active melody, simpler bassNow reverse.34.45Level 18 — destination-first improvisationTake a chain of six chords.34.46What about the intervening chords?Use:34.47Level 19 — phrase through temporary tonicSuppose:34.48This is harmonic prosodySome chords are commas.34.49Level 20 — one-note structural mapPlay the roots/chords.34.50Level 21 — two-note guide-tone mapNow give each structural arrival:34.51Level 22 — fill connectors afterwardOnly now add:34.52Level 23 — memory strategyDo not memorize:34.53Level 24 — bass-memory exercisePlay the full bass map without RH.34.54Then sing melody over bassThis exposes whether the basic counterpoint works.34.55Level 25 — shells onlyLH: bass.34.56Level 26 — rootless voicingWhen bass is implied or played by another musician:34.57Level 27 — altered dominant hierarchyIf the chord lasts only two beats:34.58Level 28 — avoid altered-scale panicIf you see G7alt:34.59This is the practical altered-scale hierarchyDestination → shell → one color → complete scale.34.60Level 29 — rhythmic simplification over complex harmonyWhen chords change quickly:34.61When harmony slowsThen you can increase:34.62Level 30 — ballad treatmentAt slow tempo, chromatic bass becomes very exposed.34.63Level 31 — medium swingAt swing tempo:34.64Level 32 — Latin treatmentA steady Latin groove can make chromatic harmony feel surprisingly grounded.34.65Level 33 — 3/4 transformationPut the progression into jazz waltz.34.66Level 34 — introA natural intro idea:34.67Alternative introBass only:34.68Which is better?First: more harmonically explicit.34.69Level 35 — endingDm7♭5 → G7♭9 → Cm6/9.34.70Final tonic choice mattersCm6/934.71Practice Loop A — chromatic bassPlay:34.72Practice Loop B — bass + fixed melodyHold G or E♭.34.73Practice Loop C — minor ii–V destinationsPractice:34.74Practice Loop D — three roads to C minorG7♭9→Cm.34.75Practice Loop E — dominant chainE7→A7→D7→G7→Cm.34.76Practice Loop F — temporary versus structural tonicPlay:34.77Improvisation Challenge 1 — structural notes onlyOne chorus.34.78Challenge 2 — guide tones onlyUse only 3rds and 7ths plus half-step connectors.34.79Challenge 3 — one chromatic lineUse:34.80Challenge 4 — phrase through a cadenceYour phrase must continue through a temporary Gm arrival.34.81Challenge 5 — one altered note per dominantOn each dominant, select only one color:34.82Ear Drill — minor line clichéSing:34.83Ear Drill — dominant destinationRandomly play:34.84Ear Drill — altered colorG7 shell:34.85Ear Drill — temporary tonic weightPlay a minor ii–V–i into Gm.34.86Mini-composition exerciseWrite 16 bars in C minor.34.87Apply it to “Happy Birthday”Now take our laboratory melody again.34.88Notice the evolution of your thinkingEarly in the course:34.89The three scales of harmonic thoughtYou should now be able to think simultaneously at three levels:34.90The deepest practical ruleWhen a progression seems impossibly complicated:•Workshop 34 mini-test1.
