Need to write a 1000 word essay about this, but I can't figure out what the poem is even about. What is the meaning & how did you figure it out? thanks

Question

March for a One Man Band
by David Wagoner

He’s *a boom a blat* in the uniform
Of an army *tweedledy* band *a toot*
Complete with medals *a honk* cornet
Against *a thump* one side of his lips
And the other stuck with *a sloop a tweet*
A whistle *a crash* on top of *a crash*
A helmet *a crash* a cymbal a drum
At his *bumbledy* knee and a *rimshot* flag
*A click* he stands at attention *a wheeze *
And plays the Irrational Anthem *bang*
