Nanopublication — Chromesthetic Translation of the Bb Minor Triad in Spread Voicing

Context

This small étude belongs to my ongoing systematic exploration of harmonic color mappings across all keys. The Bb minor chord — built on the minor third interval Bb–Db and the perfect fifth Bb–F — maps in my chromesthetic system to violet, blue-green, and red-violet respectively, following the circle of fifths architecture that anchors the system. The spread voicing, distributing chord tones across multiple octaves, becomes the compositional structure of the painting: register height corresponds to vertical position on the paper, and lower registers darken toward the bass while higher registers bleach toward light. The three chord tones are visible as the dominant hues; a trace of orange (D) and yellow-green (B) drifts outside the harmony as chromatic color. Each variation in this series is a study — focused, direct, concerned with the essential chromatic character of a single harmonic configuration.
