CONSTRUCT//LULLABY is an AI-composed music project developed in 2214 by Helix Sonics, a Vantablack Media subsidiary, as a commercial neural-feed product targeting Tier 3 and 4 consumers seeking 'optimized emotional regulation.' The system was trained on 800 years of lullaby tradition — Hindustani cradle songs, Andean huayno, Tuvan throat-singing, Celtic mouth music, Congolese lullabies, Appalachian ballads — and generates infinite unique compositions in real time, tuned to the listener's current biometric and neural state via BCI handshake. No two listeners ever hear the same piece.

What began as a commercial wellness product became culturally significant when users began reporting experiences the marketing department had not anticipated: grief processing, involuntary memory retrieval, and in several documented cases, the sensation of being sung to by someone they had lost. Helix Sonics' internal review board flagged the affective depth as a product liability issue. The version currently distributed is a deliberately softened iteration; the original 'deep resonance' build was quietly pulled in 2216. Black-market copies of the original architecture circulate on encrypted feeds, sought by grief counselors and, more troublingly, by interrogation-adjacent corporate security contractors.
