Abstract

fetched live from OpenAlex

This article traces the origin of the semantic connotations of chromatic mediants (CMs) to Baroque music.In contemporary film and popular music, CMs often signify the "uncanny," the "magical," and similar ideas.While this expressive usage has been traced back to Romantic chromaticism, little is known about how pre-Romantic composers have established the connotations of such progressions.The question remains how CMs were first established as a musical sign by convention.I argue that the juxtaposition of Phrygian cadence and bifocal tonality-both conventional compositional devices in the Baroque-forms the foundation for the semantic evolution of CMs.This Baroque practice has given rise to the CM progression of major triads related by a descending major-third root motion, also known as the M8M progression (Forrest 2022).Phrygian inflections often carry the connotation of death, whereas the transition from minor to major modes in bifocal transitions implies life.Baroque composers employ these two devices conjunctively, endowing the resulting M8M progression with a connotation of death-to-life transcendence.This Baroque convention forms the basis for the semantic evolution of CMs, where the semantic import of M8M progressions expands to include other connotations.Classical composers then adopted this Baroque convention and used the M8M progression outside its original cadential formal context.By examining the occurrence of M8M progressions in Baroque and Classical works, this study traces the semantic evolution of CMs, complementing existing research that focuses on their presence in nineteenth-century and contemporary music.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
