The craft essay's hybrid nature
The craft essay is a formally hybrid text: it combines the analytical rigor of literary criticism with the personal voice of memoir, the argumentative structure of the essay with the close reading of practical criticism, and the general claims of poetics with the specific instances of textual analysis. This hybridity is the form's strength — it can do things that pure criticism and pure memoir cannot — but it requires the writer to inhabit multiple registers at once. Writing a craft essay that holds together requires understanding which register is primary at each moment: when the argument calls for close reading, the close reading must be precise; when the argument calls for personal experience, the personal experience must be purposeful; when the argument calls for general claims, the general claims must be grounded in what the close reading has established.
