I don't know about you, but climax is really important, and people love it. I'm not trying to make a Freudian slip here, I'm just trying to extol the virtues of climax. People like reason, they like order. Just think about it, there's always order in music, no matter what type it is. All music has rules, all writing has rules. Now, let's apply some of those rules. Shakespeare, or whoever he/she was, tapped into it in Macbeth. Remember the scene at the beginning of 'the Scottish play,' when the witches are brewing away. Here we have the Weird Sisters singing their sinister song: "When shall we three meet again? In thunder, lightning or in rain?" Here we have pattern and we love it. We get all squirmy inside. Try the same line with four: "In thunder, lightning, mist or in rain?" It just doesn't feel right does it?
Well, let's fit climax into the concept of threes: big, bigger, biggest, and watch the crowds go crazy. They love it. Try this on for size. "After losing the love of his life sadness turned to grief which turned to inconsolable lamentation."
So, if you use Climax, do it in threes, because four is just a wee bit much.
There is also something for experimentation. Try working the climax backwards. "His terrible exhaustion took him from gasping for breath, to breathing harshly, to finally the realm of slow control breath where only defeat lived."
