John Darnielle of the Mountain Goats was nervous when he saw the word "process" in the title of this site. Process implies routine, and Darnielle doesn't really have a routine when it comes to songwriting. In fact, he eschews the idea. If he writes every day, it's a descriptor of his routine rather than a mandate. Keep a journal? Heck no, because Darnielle feels pretentious writing about himself. Darnielle wants to demystify the songwriting process; he doesn't want to see it as something that only happens when certain factors align. He considers songwriting, or any creative. (As you'll read, Darnielle isn't too keen on the idea of writer's block.)
That's not to say, of course, that when things are going well he won't stick to what works. For example, he wrote almost all of All Eternals Deck at his dining room table "because it just seemed to be coming out good there." He likes a certain kind of writing instrument and a certain kind of notebook. And he's stick with one guitar, even if it's not the best one, "if it seems to be giving up the goods."
