A Ballad Generator Recreates Early Yuming's Melancholy With Music Theory, Not AI
The project shows that a generative music system can produce stylistically convincing ballads by encoding music theory rules, challenging the assumption that AI training is necessary for emotional expression in music.

A developer used Claude Fable 5 to build a "Twilight Ballad Generator" that composes ballads in the style of early Yumi Matsutoya. The system encodes six harmonic techniques, melodic rules such as 9th suspensions and leaps, and a pivot modulation called the "Time River" modulation. The project tests whether melancholy can be reduced to structural musical elements rather than relying on AI training.
The developer behind the project had previously built a Beatles-style song generator using the same approach. The new Twilight Ballad Generator targets the early work of Yumi Matsutoya, known as Yuming, and implements six specific harmonic techniques drawn from her catalog: subdominant minor, the doyō progression, canon-style cliché descent, secondary dominants, borrowed ♭VII, and jazz two-five. Melodic melancholy is handled through 9th suspensions, large leaps at phrase starts, and a final unresolved sus4 chord. The generator also includes a pivot modulation from the 1984 song "Woman 'W no Higeki' yori" that the developer verified through code.
