Its parameters are: (1) a simple melodic contour with narrow pitch range and repetitive phrasing; (2) a tempo matching or slowing toward resting heart rate; (3) an address directed at or near a sleeping or drowsy child. It persists through oral transmission and written notation across generations — each performance renews the form, while the shared features (lulling purpose, simplified melody, repetitive structure) mark it as the same construct.

Lullaby is a specific type of song: an authored vocal form characterized by simple melody, repetitive structure, and the deliberate purpose of soothing a listener (typically a child) to sleep. Per Law 9: a competent speaker would call a lullaby 'a song.' The INSTANCE_OF ladder connects this PROVISIONAL leaf to an ACCEPTED general.
