STRUCTURE and POETRYSTANZAS: Stanzas are a series of lines grouped together and separated by an empty line from other stanzas. They are the equivalent of a paragraph in an essay. One way to identify a stanza is to count the number of lines. Thus:couplet (2 lines)tercet (3 lines)quatrain (4 lines)cinquain (5 lines)sestet (6 lines) (sometimes it's called a sexain)septet (7 lines)octave (8 lines) FORM: A poem may or may not have a specific number of lines, rhyme scheme and/or metrical pattern, but it can still be labeled according to its form or style. Here are the three most common types of poemsaccording to form:1. Lyric Poetry:It is any poem with one speaker (not necessarily the poet) who expresses strong thoughts and feelings. Most poems, especially modern ones, are lyric poems. 2. Narrative Poem:It is a poem that tells a story; its structure resembles the plot line of a story [i.e. the introduction of conflict and characters, rising action, climax and the denouement].3. Descriptive Poem:It is a poem that describes the worldthat surrounds the speaker. It uses elaborate imagery and adjectives. While emotional, it is more "outward-focused" than lyric poetry, which is more personal and introspective. In a sense, almost all poems, whether they have consistent patterns of sound and/or structure, or are free verse, are inone of the three categories above. Or, of course, they may be a combination of 2 or 3 of the above styles! Here are some more types of poems that are subtypes of the three styles above:Ode: It is usually a lyricpoem of moderate length, with a serious subject, an elevated style, and an elaborate stanza pattern.Elegy: It is a lyricpoem that mourns the dead. [It's not to be confused with a eulogy.]It has no set metric or stanzaic pattern, but it usually begins by reminiscing about the dead person, then laments the reason for the death, and then resolves the grief by concluding that death leads to immortality. It often uses "apostrophe" (calling out to the dead person) as a literary technique. It can have a fairly formal style, and sound similar to an ode.
