Hersh's vocal style ranges from softly melodic to impassioned screaming.
She has an occasional vibrato that punctuates some of her more dramatic phrasing.
Candid about her episodes of mental illness and despair, her songs cover a vast spectrum of topics, including childbirth ("Hysterical Bending"), love ("Tar Kissers", "Lavender"), surreal vignettes ("Delicate Cutters", "Fish"), death ("Limbo"), emotional anguish ("The Letter"), loss of custody of her first son ("Candyland"), and the shedding of a relationship's anxiety ("Snake Oil").

Simon Reynolds in The New York Times pointed to Hersh's "mesmerizing" explorations of "rage, aggression and mental chaos" as evidence of female rock artists of the early 1990s pushing against gender role boundaries to express "more than simply vulnerability or defiance" in their work.

Ann Powers, also in the Times, wrote of Hersh's musical style: "Her plastic, sometimes obsessively circular song structures emphasize staggered rhythms and extreme dynamic shifts, and her voice, a carnal cry that pushes through her body gathering up air, lends her often oblique lyrics an oracular veneer."
