“Brilliantly synthesizes Hass’s formidable gifts as both a poet and a critic and reflects his profound education in the art of poetry. Starting with the exploration of a single line as the basic gesture of a poem, and moving into an examination of the essential expressive gestures that exist inside forms, Hass goes beyond approaching form as a set of traditional rules that precede composition, and instead offers penetrating insight into the true openness and instinctiveness of formal creation.”
