Destroy the Big Bad

Four
    An Hypothesis


I exhausted Carroll's rewritten ode, Jabwocky, soliciting essential clues to fully explain my difficulty.
"A Heisenberg Twinge could have modified books' contents thusly, but (my dubious thinking declared) surely these mutations are willed. I could sit and research a quantity of poetry's excellent, famous passages, or try uncovering the structures."
I therefore chose to scrutinize the words, and deliberate. I pondered games of alphabets, verses, language, sentences, equations, words. Lifting feather and inking it, my quill carefully scribbled thus:

    A few schemata involving linguistical play

    Lipograms:  Writing so a letter's missing
    Haiku:  An uncommon ode (poem) bearing eccentric metrification characteristics
    A Cento:  Quite strange poem; borrowed lines
    Anagram:  To turn an item (words) into a novel expression
    Double-entendres:  Words, dualistic sense
    Palindrome:  Forwards or backwards, words are not transformed ("Redraw, detooted warder!")
    A pangram:  An amazing sentence, using whole alphabet
    Acrostic:  Inspected vertically, letters spell additional statement
    Mnemonic:  Can remember a factoid using this device
    Pun:  Groaner ("Stop, pundit!")

Thus utilizing the plumelike pen, I hesitated.
"To cause these variations surely insinuates much diabolical, innovative ingenuity. My poetry's clearly overturned; I cannot, however, rationalize. The [repeating] diabolical, innovative ingenuity! Although most beguiled, actually I'm near exhaustion. I am defeated, quite defeated, and undone!", I yelled.
Truthfully, the eerie enigma was greatly intriguing. Reading afresh Raven's discourses, I considered many options - a palindrome, a mnemonic, a conundrum.
"Full of mysteries, these poems crave observant review," I announced. Thoughts involving rest stayed, however, slowly causing lethargy.
"Now," (quietly said) "this sojourner will seek serenity. To bring sleep, the Musical Anthology usually renders help." Turning to "Poetry, Anderson", thus emerged a remarkable poem suggesting Jon's musical group, Yes.
