Divinely “stepping rhythm:” blankverse–thou,
Most courtly poetess, to me once wrote–
To promenade as flawlessly anon.

I am tempted to write simply “‘Nuff said.”  But once again, you will already understand the meaning, so can concentrate on the sounds instead of the other way around.   There are not so many changes as one might expect.  And we are very close to a sonnet.  In fact there are, by various authors, many sonnets written in this way.  No rhymes, just blankverse.  They often sound quite lovely either way, depending on the poet, and whether you do or do not like his style or subject matter.
