The Clank of Narrative.

In a review in Entertainment Weekly of director Mike Leigh's new (and critically acclaimed) movie, Another Year, writer Owen Gleiberman praises the movie as free of "the clank of narrative." 

He's talking about a loose style of filmmaking, driven not so much by action as by observation.

But this applies to writing as well.  If words clank, then they clearly don't work.

My advice is to loosen up.  Listen to each word and determine if it dances on the page, on the tongue, in the ear.
