One of the things I like best about Young Wizards is the parts that I can only describe as sublime and transcendent. How do you write something transcendent? I’ve tried, and it only ends up sounding silly, so now I don’t try anymore.
I think if I tried to write transcendent, it would come out silly for me too.
What seems to work is to write in styles that suit the content. Be goofy when humor’s okay, be sparse and concrete and visceral when fear is in the air, be grave when gravity is appropriate, be lyrical when the material tempts you to it (because usually the urge can be trusted). Let what’s going on dictate the tone: and don’t be afraid to stretch around inside your own writing style. Always be looking for a better way to say whatever’s there to be said.
I think if you do that, then you’ll get lucky and get transcendent for some people. But it needs to be in the back of your mind, not the front. Someone said that the fire from Heaven won’t descend until you’ve built the altar to receive it. So build the altar, but keep your mind on the bricks and mortar. The fire will take care of itself.
