Abstract
Primary caregivers throughout the world provide infants with life-sustaining care such as nutrition and protection from harm as well as life-enhancing care such as affection, contingent responsiveness and mentoring of various kinds. They nurture infants musically by means of one-on-one (i.e. infant-directed) singing accompanied by movement in some cultures and by visual gestures in others. Such singing, which is acoustically and visually distinct from solitary (i.e. self-directed) singing, is effective in engaging infants and regulating their mood and arousal. The repetition and stereotypy of caregivers’ performances contribute to their memorability and dyadic significance. Caregivers’ singing also influences infants’ social engagement more generally. Once infants become singers, their songs play an important role in social interaction and emotional self-regulation. Although caregivers sing to infants with playful or soothing intentions, their performances highlight the temporal and melodic structure of the music. In sum, caregivers lay the foundation for a lifelong musical journey.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
