As far as rhythm is concerned, the poem seems to lack a support, an expected tonicity in specific syllables, so that there is a sense of harmony and that the planned breaks can stand out. If the rhythmic pattern varies with each verse, there is no pattern and therefore no rhythmic base on which the verses rest. Unless one avowedly makes poetry by stripping it of musicality, the much-criticized regularity seems a necessary condition for poems that are meant to be good.
