Prosody

In a dinner with department members and a visiting speaker, someone asked me about versification. What was the equivalent of the Spanish romance?  I started to talk about the ballad form, its history and prosody.  I cited Robert Burns, My love is like a red red rose. I mentioned that it was the same as the stanza used in many hymns by Isaac Watts.  En fin....  They asked me about the Alexandrine...  I was like, don't get me started.  I could have lectured all night.
