🎙 Vocal Voice Leading & Dynamic Ribbons

In late 90s and 2000s R&B (pioneered by Brandy, Ray J, Rodney Jerkins, and Bryan-Michael Cox), vocal counterpoint relies on close-interval movement over extended major 9th and minor 11th chords. The visual ribbons above show real-time pitch spacing between the lead melody line and harmony counter-lines.

🎼 Consonance Ratios & Extended Voicings

Harmonic interval Major 3rd generates a clean 5:4 frequency ratio. This Creates low acoustic beats and optimal acoustic warmth without cluttering the bass or root piano voicings.
