"Home Burial" represents Robert Frost writing in the avant-garde style of poetry that arose, beginning early in the twentieth century.
Avant-garde can be defined as meaning "the invention and application of new techniques in a given field" and frequently is used particularly to describe new innovations in artistic areas. In the field of poetry, avant-garde poets were involved in experimenting with using new formats for their poetry, no longer restricting their writings to predictable rhythmic and rhyming patterns.
Frost abandons rhyme and uses blank verse in "Home Burial," which was published in 1914. While the meter is not obvious, the pattern of iambic stress is present.
He saw her from the bot-tom of the stairs
Be-fore she saw him. She was start-ing down,
Look-ing back o-ver her shoul-der at some fear.
