National Poetry Month

Ballad-A narrative poem consisting of quatrains of iambic tetrameter alternating with iambic trimeter. Common traits of the ballad are that (a) the beginning is often abrupt, (b) the story is told through dialogue and action (c) the language is simple or "folksy," (d) the theme is often tragic--though comic ballads do exist, and (e) the ballad contains a refrain repeated several times.

Epic-A poem consisting of (a) a long narrative about a serious subject, (b) told in an elevated style of language, (c) focused on the exploits of a hero or demi-god who represents the cultural values of a race, nation, or religious group (d) in which the hero's success or failure will determine the fate of that people or nation. Usually, the epic has (e) a vast setting, and covers a wide geographic area, (f) it contains superhuman feats of strength or military prowess, and gods or supernatural beings frequently take part in the action.

Haiku-Japanese haiku consists of three lines. The first line contains five syllables, the second line contains seven, and the last line five. The traditional subject-matter is a Zen description of a location, natural phenomona, wildlife, or a common everyday occurrence

Lyric-A short poem (usually no more than 50-60 lines, and often only a dozen lines long) written in a repeating stanzaic form, often designed to be set to music.

Monologue-A poem in which a poetic speaker addresses either the reader or an internal listener at length. It is similar to the soliloquy in theater, in that both a dramatic monologue and a soliloquy often involve the revelation of the innermost thoughts and feelings of the speaker.

Ode-A long, often elaborate stanzaic poem of varying line lengths and sometimes intricate rhyme schemes dealing with a serious subject matter and treating it reverently. The ode is usually much longer than the song or lyric, but usually not as long as the epic poem.

Sonnet-A lyric poem of fourteen lines, usually in iambic pentameter, with rhymes arranged according to certain definite patterns. It usually expresses a single, complete idea or thought with a reversal, twist, or change of direction in the concluding lines.
