Caroline Calloch says of Sibille's work: "Her verses have the musical quality of a score. Language serves as a substitute for notes and forms a libretto . . . Roselyne Sibille's word music vibrates between two poetic silences." She has published several collections and collaborative works, including Lumière froissée (with paintings by Liliane-Eve Brendel), Par la porte du silence (with Bang Hai Ja), Versants and Tournoiements.
