Gregory Orr is the founder of the MFA program at the Univ. of Virginia, so I guess this means he decided to write his own "Introduction to Poetry" book for student readers and writers, but you needn't be a student to appreciate his plain speaking (something that's always appreciated in Poetry World).
The book stops for creative writing exercises, but I sort of skimmed over those (hey, I'm auditing this course!). My hands are full with my own assignments. That said, you might enjoy them if you're an aspiring poet or even an established one.
For starters, Orr gives a pep talk on letting it rip when it comes to writing. Block? That's for sun sauce, baby. When it comes to writing, first drafts are places to spill. You can pick through the wreckage later (garbage picking always yields treasure, after all).
Next he distinguishes between narrative and lyric poems, giving characteristics and examples of both. In his view, narrative often needs MORE during revision and lyric LESS.
From here he divides poetry's essentials into four parts: Naming, Singing, Saying, and Imagining. Naming is where your powerful vocabulary comes in. If you're writing about what you know (or even attempting to write about something you've never experienced), you'd better know what things are called. Specific nouns and action verbs are king and queen of the land, after all. Adjectives and adverbs? Not so much. Orr's exception is color words.
Singing brings us to the music of poetry. Orr reads all his poems aloud and says you should too. In the poet's conservatory you'll find such tools as rhythm and meter, diction, vowel pitch, assonance, consonance, incantation, syntax, anaphora, and other tricks of the ear trade. All together now on Middle C!
Saying goes into pronouncements. Acting like you own the place. The way certain lines of poetry are memorable because they seem so wise and deep. I'm just saying.
And finally Imagining, which is a love song to metaphor. Nothing like a good metaphor, but there's something about bad ones and mixed ones and tired ones. Beware, in other words, but know that this is an essential tool of every good poet.
A lot of the example poems are from OBG's like Walt Whitman (heavily), Miss Emily, WB Yeats, Theodore Roethke, T.S. Eliot, and Pablo Neruda. This may be because getting permissions from more modern poets is a royal (royalty?) pain, so the go-to for books like this is the public domain.
Enjoyable, overall, and suitable for folks who want to learn more about poetry OR who know a lot about it but want to get some inside tips and drills. Good for strictly readers of poetry and good for writers of poetry (who of course read poetry). One of the better ones of this ilk, when all's said and done (and for me, it is).
