Haegue Yang's *Sonic Half Moon Type IV - Small Regular #12* is a striking sculptural work that exemplifies her ongoing exploration of sensory experience and geometric abstraction. The piece likely incorporates her signature use of venetian blinds, bells, or other kinetic and sound-producing materials, inviting both visual and auditory engagement. Through its precise, modular form, the work reflects Yang's interest in rhythm, movement, and the interplay between structure and perception.
