The phrase “pace and poise” seems to be a sort of idiom, albeit I can’t find any reference of it being one in the dictionaries I can avail myself of. I have come upon the phrase in the following passage taken from the New Yorker (emphasis added):
But something happens to the pace and the poise of “Django Unchained” as the hunters head South and the screen fills with the word “Mississippi.”
While I perfectly know the meaning of each word this phrase is constituted of, I think that there is something more to the mere addition of each meaning which I cannot grasp at the moment. Is this an idiom?
