I guess I am still not sure what you are looking for here. If you study either verse or music, you'll find that there are sufficient terms for analyzing everything, and at any level. The proof of this is that it is possible for people to learn the rules for writing in any genre, though of course the quality of their work depends on the writer(some of the people around here have managed to write narrative ballads that would pass for traditional, though the subject matter is often contemporary)--

There are a lot of websites that feature the rules of verse, with greater or lesser levels of depth, if that is what you are looking for--as for the musical part of things, the definitive work is most likely Nicholas Slonimsky's "Thesaurus of Scales and Melodic Patterns"--
