Workshop 60 — “Butterfly”-Type Floating Harmony: Deep Pocket, Pedal Centers, Upper Structures, Parallel Voicings, Common-Tone Motion, and Making Harmony Feel Suspended Rather Than Functional

Workshop 59 focused on microtiming and pocket.

Now we keep that deep pocket but change the harmonic world.

Instead of:

chord → dominant → resolution

we explore:

a tonal center that stays present while upper harmony seems to float above it.

This is a major sound in modern jazz, fusion, soul-jazz, neo-soul, and modal arranging.

The central lesson is:

Harmony does not always need to “go somewhere.” It can hover, rotate, and change color around a stable center.

principleThe 3rd determines chord quality very strongly.32 words60.7Level 1 — one bass, three upper colorsKeep C-G bass.29 words60.8Analyze Color CE♭-A-D over C:18 words60.9C DorianC Dorian:33 words60.10CompareC pedal.21 words60.11Level 2 — color without root changeSpend four bars on:26 words60.12Harmonic movement can occur vertically rather than geographicallyTraditional functional harmony often says:35 words60.13Level 3 — upper-triad thinkingKeep C bass.26 words60.14B♭/CB♭-D-F over C gives:17 words60.15Dm/CD-F-A over C:11 words60.16F/CF-A-C over C:19 words60.17Level 4 — rotate upper structuresKeep C.25 words60.18Why slash-chord thinking is usefulInstead of memorizing a giant chord symbol like:35 words60.19Level 5 — parallel movementNow keep a three-note RH shape and move it.28 words60.20Classical warning that no longer applies rigidlyParallel movement would be heavily restricted in certain classical voice-leading contexts.42 words60.21Level 6 — planingPlaning means moving a chord shape in parallel while preserving its intervallic structure or approximate identity.33 words60.22Two kinds of planingsame interval structure moves.27 words60.23Level 7 — common-tone anchorHold G in top voice.24 words60.24Fixed pitch, changing functionG over C: 5.28 words60.25Level 8 — bass finally movesAfter eight bars of C pedal:36 words60.26This is why bass movement feels huge after a long pedalIf roots change every half-bar:26 words60.27Level 9 — return to C without dominantF → C.23 words60.28Level 10 — introduce dominant only onceAfter a long modal section:23 words60.29G7alt

words60.35Level 13 — chord fragments rather than full changesInstead of sustaining whole voicings:26 words60.36Less vertical thinkingDo not always think:26 words60.37Level 14 — melody can define the chord identitySuppose upper harmony omits 3rd.39 words60.38Level 15 — suspended dominant as tonic-like colorPlay:21 words60.39Then reveal EChange F→E.15 words60.40Level 16 — ambiguity is a resourceYou do not always need the listener to know:23 words60.41Level 17 — pedal with chromatic upper structuresKeep C.29 words60.42D♭/CD♭-F-A♭ over C:9 words60.43D/CD-F♯-A over C:20 words60.44E♭/CE♭-G-B♭:24

riff has one rhythmic pattern.22 words60.54Level 25 — one common upper note across planingKeep D on top.25 words60.55Double pedal conceptNow you may have:18 words60.56Level 26 — melody as pedalHold

chord-symbol panicWhen playing this kind of harmony, you may encounter voicings that can be named several ways.55 words60.61Level 30 — functional cameoAfter a long suspended/modal world:29
