Pacing, eh?
Let me grind it down to its most simple, basic element in the following statement:
Effective pacing is being able to go from slow to fast or fast to slow in the appropriate places in your story to not only hold your reader's interest, but their emotions.
The thing is that page turners are page turners for a reason. While many discredit
Harry Potter as being an example of poor writing that many simply bought into, I have to disagree. It is one of the top 3 most printed books of all time, I believe, up there with the Bible and The Lord of the Rings (which has also been discredited). To refuse to learn from Harry Potter, claiming it to be purely a commercial success, is to discredit all those who read it, and to give up perceptiveness, one of the most essential traits among writers. That being said, Harry Potter, especially the early novels from which the books exploded, do an almost mystical job of pacing. Many times, for research, I've found myself being instead drawn into the story of book 1 and reading half the book before I look up at the clock and remember that I'm supposed to be an analyist of this story right then, rather than an engrossed reader. It
seems as though the pace is high-speed, but that is only the speed at which you read. The pace of the story is actually down and up constantly, as Rowling grabs you with her words, whatever page you flip to, and sends you on a ride of emotion from which you're not likely to get off unless you suddenly become aware of what's behind the scenes and grow jealous. Bad idea.
What is behind the scenes, though? Let us turn back to pacing.
In the most general sense, as talked about before, this is the concept of the balance between going too slow and too fast in a story. Both will drive the reader out of the story, no matter how pertinent or well-constructed your story is. Do not give tranquility without challange, harmony without tension, peace without danger, normalcy without interruption, or relaxation without fear - You get the idea. You need to create a mix of harmony and tension, slow and fast, that flows on the micro level while, on the greater scale, you have progression. Pacing, however, is between action to reaction within the scenes, the scenes themselves, the sequences of scenes, and the Acts of your story. While not everything may be cut and dry Slow-Fast-Slow-Fast, especially on the greater scale, to pace well you will indeed have variance, or else you will bore the reader. It doesn't matter the content or the awards you win for philosophical masterpiece of the year. You want to resonate with your readers, who are attuned to the variance of life and that desire of duality of pace.
For instance, let's look at the 2nd chapter of
Harry Potter and the Sorceror's Stone - you can read an excerpt here at
http://www.kidsreads.com/clubs/club-sorcerers_stone-excerpt.asp
Slow: The chapter opens with a description, which can be considered at going a slow pace, but this rides off the fast-paced ending of the cheer ("To Harry Potter, the boy who lived!") at the end of the last chapter, which was big motivation for coming to this chapter anyway. Also, even this slow spot is "fast" because it covers 10 years of time in one paragraph, and gives some gratification for the history foreshadowed in the first chapter.
Fast: Harry gets woken up "with a start", also bringing us back to his position. After he flicks off the spider from his sock, this brings us into slow speed again.
Slow: Further gratifies us with more on the result of Harry going to live with the Dursleys, which was foreshadowed by their disapproval of the Potters and the excellent set up of character in the first chapter, which we now see manifested in Dudley. This also provides a contrast to Harry. The humorous description which builds sympathy for the MC takes that subject and adds a little more info him as an individual, in particular, him in comparrison to the Dursleys, though they aren't the main subject of the second part of this section.
Fast: Within the description, the line "And don't ask any questions" concludes the frustration of living with the Dursleys for the slow segment with clarity. This is very short fast section, ending with Uncle Vernon shouting at Harry about his hair.
Slow: More background, but short, making us want more, as we know there is more to Harry than just his hair growing wild. The second part of this section, however, gets our mind off of that by showing us a picture of Dudley that contrasts Harry from both Dudley and Aunt Petunia: "and thick blond hair that lay smoothly on his thick, fat head. Aunt Petunia often said that Dudley looked like a baby angel--Harry often said that Dudley looked like a pig in a wig." This settles his difference on the subject of hair with every member of the Dursley family.
Fast: We grow even more discussed with the Dursleys as Dudley cries about his presents and gets gratified by his parents.
Slow: This interesting slow segment when the phone rings is a point of interest. The slowness here actually draws us in so we realize that this is a turning point, but just slow enough so that the next part falls in line with our own emotions.
Fast: Petunia asks "Now what?" just as we do, our heart leaping for Harry who has our sympathy in this loony bin of a family. The background tension here launches a set of dialogue that moves quickly, but slows down partially in the middle to help us in hating Dudley for crying in this moment of glory. The scene is on Dudley's side when we hit the slow section.
Slow: This gives the conclusion of the scene first, in which Harry gets to go to the zoo, which leads into the second section. More background, made pertinent by the fast section, and gratifying some more of the anxiety of the offset worlds of the first chapter where we have already seen wizards. Even this part has a mini-pace to it, progressing from small, humorous magical occurances to even more doubtfully normal cases in which Harry is forced to come to logical conclusions. Then it goes to "But today, nothing was going to go wrong.", which, from the pacing of the examples, we scoff at, knowing that logic is folly, and not only will something go wrong, but it will be a magical sort of thing. Still- we want to find out
how. It then snaps back to the moment.
Fast - snapshot of an inconsequential moment that reveals much about every moment with the Dursleys through that inconsequence, and a great example of what Harry has to deal with, living with magical reality mentioned in the slow segment before.
Slow - Entering the zoo. No description is wasted, poking further fun at Dudley.
Fast - Brings the slow section to come into perspective with a single scentence: "Harry felt, afterward, that he should have known it was all too good to last."
Slow - Sets up the scene and the problem: the snake won't move. We are pulled alone emotionally by Dudley not being gratified - something we wanted all chapter.
Fast - Our pulse quickens as the snake raises its head while only Harry is looking, and we are hooked beyond measure of putting the book down when it winks.
Slow - Harry and the snake have an exchange, which is slow but tense, noting the air of mystery and excitement surrounding this encounter.
Fast - Dudley butts in. The scene turns when the glass disappears, and continues to hold us till the snake is gone and sufficent people have screamed.
Slow - A long passage settles in the injustice of his reality with us, engraining the irony of magical experiences without understanding or appreciation for them. Even though the two scenes in the chapter ended up, the chapter as a whole ends down, creating irony that binds us to the MC, and helps us to feel his pain at having to live in abject tyranny, the "magic" of such experiences as the one at the zoo being offset by an oppresive sense of logic. We see alot wrong in this scene, and what should have turned out good went bad, though we knew it would all along- it could have ended no other way. But we want to see it end another way, so we turn to Chapter 3.
THAT is pacing at its finest. We ride along, and tension builds because there is forshadowing placed at strategic points in the chapter off of which to base further conflict, fast leads to slow and slow to fast with seeming effortlessness, but building the conflict till we get the extremes of possibility presented in the chapter in truely ironic fashion: Harry has a supremely gratifying magical experience that grants his revenge on Dudley, who we've grown to dislike more and more throughout the chapter, and then Harry gets punished for it, prolonging our sense of injustice and deeping our desire to have Harry get out of that mess and find out who he really is.
This is what I meant by being able to learn from effective pacing. Whether in a movie, play, or novel, you know when your attention has been grabbed through effective pacing, and you don't have to justify why you're watching or reading what you are. Rather, you might feel something devious in it, and seek to discredit it somehow to protect yourself from its effect on you. If you catch yourself doing that, instead recognize its effectiveness and analyze it. Whether or not it is based in moral, deep, probing themes or questions about our reality is an entirely different matter.
Hope that helped
EDIT- As a further example, I noticed that my post is a BAD example of pacing, but that was for necessity, and I wasn't in the midst of writing a story. I go from slow to fast to slow to fast for way way too long, then back to slow for a few lines too long, then summing it up with one line of fast. A lesson within a lesson!
