So you exercise your tongue, and it gets stronger and more aware of what it can do. That's the first order of business. And then when you plop off the nipple, you look up, and what's waiting for you there? Two huge amazing wonderful shiny things. Your mother's eyes. And below that is a strange item with two nostril holes, and then there's a single large flexible opening at the bottom, which moves around a lot in an interesting way, and out of it issues all this marvelous taffylike goopy stuff that you can't see but that goes into your ears. It's impossible to make sense of it, but it's nice, and you like it. Something deep in you tells you to listen to it. It's speech. And when your mom's mouth smiles you learn the color white.
The mouth says, "A boo boo boo! Yes, my little fumble nuggets! A noo noo noo!" Aiming the sound at you. Talking to you, in other words, in a particular tone of voice. And thoughtful people have studied this tone of voice, and they understand that this is not something to be lightly dismissed. This talk is the crucial ingredient. This is the way that the genetic memory of speech is being imprinted on a new practitioner.
Baby talk, which is full of rhyme, is really the way you learn to figure out what's like and what's not like, and what is a discrete word, or an utterance, and what is just a transition between two words.
How does it happen? Well, it happens gradually, and it happens by matching. Matching within and matching without. First you have to learn that a certain feeling in one part of your body, your tongue, matches with a certain feeling in your brain, which is a sound. A slightly different feeling in your tongue matches with a different sound coming out of your mouth and a different sensation of muscular control registering in your brain. Each subtle difference of sound feels different. And this is all very difficult and takes lots of trial and error and babbling and drooling and lip popping and laughing.
Of course, you're doing a lot of random sudden things at that point. Your eyes dart left. Your fist suddenly goes boing! Sticks out. Head swivels. Whoa. Back arch. Leg. Sudden diaper squirt. Things are happening everywhere. And each one of the things that happen, the random little twitchy things, sends a message to central control that feels a certain way. So you begin to correlate. And your mouth turns out to be probably the most important piece of the pie. When you cry you get results, and when you suck you get milk, and when you go "Nnnnnng!" the face above you smiles and goes " 'Nnnnng,' what do you mean 'Nnng,' you funny little baby?" Reflecting it back.
And you start to see that all these sounds that you can make-ngo, merk, plort-that you begin to hear, can be classified in certain ways. You're a newborn brain, you've only recently come out of solitary confinement in the uterus, and you're already a cryptanalyst in Bletchley Park. You're already parsing through, looking for similarities and differences, looking for patterns, looking for beginnings and endings and hints of meaning.
ESPECIALLY BEGINNINGS. The beginning of a sound is usually a moment where you forbid the sound to be produced. With your lips. Puh, buh, bluh. Or you attempt to dissuade it gently: nnn, mmmm. You put some sort of barrier or seawall there, and then you remove it to allow the sound to unfold itself briskly into a vowel. Unfold the vowel towel and floom it out and let it settle on the sand. Flume, broom, room, spume, gloom, doom.
So you've got the beginning, which is generally a consonant, and then you've got the middle of the sound, which is often a vowelly region. And then you've got the end of the sound. And all these things are difficult to make out. We know from speech-recognition software how hard it is for a computer to figure out where things begin and end. It's like looking at the horizon and thinking, Is that lump Mount Monadnock or is Mount Monadnock that lump there? Actually Mount Monadnock is pretty distinctive. But sometimes when you look at a mountain range it's very difficult to know what's what.
Do you care how things are spelled? Obviously not. Spelling? What's that? That's absurdity. That's a whole different layer of opacity-the layer of squirming black shapes on a page. That's years in the future. What you're doing, inside your head, is classing things by sound shape. And by detachable head. And that's where rhyme comes in.
Think of what happens when you say the word "moon." What does the speech part of your brain do? It says, Okay, assignment: moon. Jaw down a bit, lips together. And flatten. Good. Then commence huffing out some sound. Constrict the vocal cords. Mm. Now open and flute the lips into an O shape. Ooo. Moo. And then terminate by flipping up the bottom of the tongue and lightly caressing the roof of the mouth. Airtight seal. And out the nose. Moon-ah. And you're done.
That's all your mouth control center knows. It knows a series of muscular commands. It does not know spelling or meaning. And because it's an efficient mouth control center, it classes that series of muscular commands as being very similar to one next door to it: rune. The end is the same, and it's going to store that near "moon," but it's going to give you a different beginning. It's going to say, Okay, go back in the back of your mouth, I want you to do something kind of difficult with the back of your tongue. And then I want you to flip your tongue up. Rrr. Don't roll it! Don't roll the R, don't trill it, because you are not Sarah Bernhardt. You're not William Butler Yeats. You're just going to say "rune."
The tongue is a rhyming fool. It wants to rhyme because that's how it stores what it knows. It's got a detailed checklist of muscle moves for every consonant and vowel and diphthong and fricative and flap and plosive. Pull, relax, twitch, curl, touch. And somewhere in there, on some neural net in your underconsciousness, stored away, all these checklists, or neuromuscular profiles, or call them sound curves, are stored away, like the parts of car bodies, or spoons, with similar shapes nested near each other. Broom and loom and tomb and spume and womb and whom are all lying there on the table in one spot. And you figured all that out by yourself. They rhyme.
And what's different about them? The all-important beginning. The removable hair. Or the wig. The sound has a body, a sort of a snaky thing, with a little bell on its tail. And then when you get up to the head, the head can have a bunch of puffy P kind of hair on its head, poom, or a fluffy FL kind of hair, or a dark black M hairdo, or big blowsy bastardizing hair. You can have all kinds of hair preceding that oom sound.
Buh. Hoo. Huh. Hay. And once you've got them classed and labeled, you can start taking off and putting on the sound-wigs. You pick up "plume" and you carefully, patiently, take off the PL and you put it aside. Don't drop it! And you pick up the BL, put that on. Get it properly adjusted. Brrrrrr. Brrrroooom.
So what rhyming poems do is they take all these nearby sound curves and remind you that they first existed that way in your brain. Before they meant something specific, they had a shape and a way of being said. And now, yes, gloom and broom are floating fifty miles away from each other in your mind because they refer to different notions, but they're cheek-by-jowl as far as your tongue is concerned. And that's what a poem does. Poems match sounds up the way you matched them when you were a tiny kid, using that detachable front phoneme. They're saying, That way that you first learned language, right at the beginning, by hearing what was similar and what was different, and figuring it all out all by yourself, that way is still important. You're going to hear it, and you're going to like it. It's going to pull you back to the beginning of speech.
