Hard Rock Blues — Riff-First Bar Story

A hard-rock-blues song. Riff identifies the song in 8 seconds. Blue-collar concrete register — a specific factory, a specific 1978 truck, specific names. Time-to-hook ≤ 30s. Percussive consonants (hard /k/, /t/, /p/) on stressed peaks. Open-vowel chorus payoff.

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 Hard Rock Blues.
