Alicia Ostriker:

All poets have their chosen ancestors and affinities. As an American poet I see myself in the line of Whitman, Williams, and Ginsberg, those great enablers of the inclusive democratic impulse, the corollary of which is formal openness. As a student I wrote in traditional closed forms, as did they—before they discovered the joy and meaning of open forms. To write in open forms is to improvise. Improvisatory verse is like doing a jazz solo: we know what we’ve just done, and the next line has to be connected to it, has to grow out of it somehow, but there is an essential unpredictability. This is an American invention because we act, in America, as if the future is partly shaped by the past, but is not determined by it. We are (a little bit) free.
