Workshop 26 — “’Round Midnight”: Chromatic Melody, Diminished Color, Altered Dominants, and Making Dissonance Sound Beautiful

This workshop introduces a different problem:

What if the melody itself is chromatic enough that the harmony cannot be understood as “simple tune + fancy chords underneath”?

In “’Round Midnight,” melody and harmony are tightly intertwined. The expressive character comes from:

This makes it an excellent laboratory for learning how melody can generate harmony.

We’ll work conceptually around C minor, rather than reproduce a complete lead sheet.

The central lesson is:

Chromatic notes stop sounding “outside” when you can hear exactly what they are leaning toward.

26.1Start with minor tonic again — but differentlyYou already know these colors:45 words26.2Why Cm(maj7) sounds so specialIt contains:50 words26.3Play this comparisonC-E♭-G-B♭25 words26.4Now

chromatic chord.28 words26.12Example: A♭ over CmA♭ is:35 words26.13Level 2 — melody generates chord colorNow do the opposite.37 words26.14Top-down harmonyYour procedure becomes:22 words26.15Level 3 — diminished chord as tensionFully diminished:43 words26.16Play B°7 → CmSlowly.26 words26.17Compare G7♭9 and B°7G7♭9:28 words26.18Two ways to hear the same tensionG7♭9 → Cm.17 words26.19Level 4 — choose by bass lineIf bass wants:22 words26.20ExampleBass:43 words26.21Level 5 — diminished passing motionTry:25 words26.22Another diminished connectorFm → F♯°7 → G720 words26.23Fully diminished symmetry

words26.26Diminished vocabulary should sound directionalA diminished arpeggio played randomly can sound like an exercise.22 words26.27Level 7 — dominant ♭9In C minor:23 words26.28The ♭9A♭.16

voicing:17 words26.33Do not play this lowKeep altered notes above middle register.15 words26.34Level 9 — altered melody against dominantSuppose melody = A♭.30 words26.35This is the voicing ruleIf
