The Vivaldi of poets has also been accused of "some hazy notion of an analogy between music and poetry". Whether hazy or not, the notion colors such poems as "Harmonium"s "Peter Quince at the Clavier" and "Infanta Marina", which Vendler likens to a "double scherzo". She also observes that for Stevens "looking and hearing, imagery and musicality, occupy equal ground". Essayist Llewelyn Powys also pursues this notion, finding that "each unexpected verbal manipulation conceals some obscure harmony of sense and sound which not only provokes intellectual appreciation, but in the strangest possible way troubles the imagination". Anca Rosu gives priority to sound: "To Plato's metaphysics of sight Stevens responds with a metaphysics of sound."
