Quick facts
Parent arc · SA#27
“At rock altitude, the vowel must yield to the pitch.”
The first arc to ground a Sacred Accident in measurable formant physics. Above ~G4 chest voice, F0 collides with the structural formant of closed vowels — the singer reshapes mid-note, breaking the chorus payoff. The Vowel-Pitch Integrity primitive flags closed-vowel cliffs at chorus peaks. 5 substyles span classic-rock-radio → roots-heartland, each with its own VPI ceiling.
The load-bearing primitive is VPI — applied to every rock lyric the forge produces, including Prog Rock Literary.
