solo style

The mark of a great poet is that the work is such that it cannot set off a style. Some may imitate its most superficial aspects, but the work begins and ends with that poet.

singularity

Whether you listen to a piece of music, or a poem, or look at a picture on a jug, or a piece of sculpture, what matters about it is not what it has in common with others of its kind, but what is singularly its own.

—Basil Bunting, The Codex
