Some poetry falls into a broader category for which there is a specific tradition. These types do not necessarily have to take a specific form. For instance, a love poem does not have to be a sonnet. They are grouped more by the subject matter than the form. For instance, the serenade and the aubade are poems for lovers. The serenade is an evening poem celebrating the meeting of the lovers for the night; whereas, the aubade is a dawn poem, usually about the parting of lovers in the morning. Because these are looser in their definitions, there may be overlap. A poem might well fit into several of these categories. Within our forms section, you will find these under Subjects and Subgenres.
