EDIT: OK I fail at quoting (also I can't type) so...
I think the structure of the poem gives information in itself, or it CAN... kind of like music gives information that the words of a song alone don't.
from SEA FEVER (Masefield)
I must go down to the seas again, for the call of the running tide
Is a wild call and a clear call that may not be denied...
This poem sounds like being on a boat riding the waves. Then a commonly cited one for rhyme scheme:
From LOVE SONG OF J. ALFRED PRUFROCK (Elliott)
Let us go then, you and I, When the evening is spread out against the sky
