Emotional Truth
The ring-test: does it feel true? Earned emotion, unforced vulnerability, no borrowed sentiment.
What good looks like
The emotion arrives through specificity and honesty, not through telling the listener what to feel.
How SongForgeAI scores it
emotional-arc.ts (Build 945) tracks per-section valence + arousal, flagging flat arcs and mis-calibrated landings. Panel judges whether the named emotion is earned by the details below it.
Common failure mode
Telling instead of showing: "my heart is breaking" where a specific external detail would do the work.
What it looks like in the wild
- A devastating line that never names the feeling it produces.
- A verse that builds pressure through detail and releases it in the chorus without italics.
- Restraint — the song that whispers where a lesser version would scream.
