Read it out loud
Keats used some very beautiful metaphors in this poem. Of course it is always a bit frustrating to pause and read the footnotes, but after I had read it the first time, I read it out loud. I don't do this very often because it's not too often that I find myself alone and comfortable enough to relish in the language without feeling strange by reading it out loud. I felt like I was able to fully appreciate the rhythm (and I'm still trying to fully understand how to write in iambic pentameter for Brit Lit, so that helped too).
This was really helpful for Brit Lit. I did not, however, read it out loud but I might...when no one is listening :).
