" A poetic form is essentially a codified pattern of silence. We have a little silence at the end of a line, a bigger one at the end of a stanza, and a huge one at the end of the poem. The semantic weight of the poem tends to naturally distribute itself according to that pattern of silence, paying especial care to the sounds and meanings of the words and phrases that resonate into the little empty acoustic of the line-ending, or the connecting hallway of stanza-break, or the big church of the poem's end.
