I know this because on my way back from class on Monday, February 24, 1975, I was struck with musical inspiration. I ran into the lobby of the dorm and groped about at the piano, coming up with music for the first few lines. Over the next few days, finishing on March 1, I wrote music for the rest of Coleridge's masterwork. But that's not important now.
Above is an article from the February 1962 English Journal about "Kubla Khan."
For a Fall 1977 class called "English Literature -- Romantic Poetry, I wrote the above brief paper. (I was more proficient in student-speak back then.) The notes, corrections, and A-minus grade are from the longsuffering Harbour Winn.
That same semester, for my student teaching at OKC's Northwest Classen High School, here was my lesson plan for introducing "Kubla Khan" to 11th-graders using a Jethro Tull song as a gateway or cross-reference.
PS remember the Star Trek TOS episode about the Salt Vampire, "The Man Trap"? Well, one of the early titles for that story by George Clayton Johnson was "Damsel with a Dulcimer," referring to the Salt Vampire's ability to enchant its prey.
If you haven't dived deeply into Kubla Khan, you're missin' out on dreamy, fascinating', charming, and creepy poesy.
