Wistful and Angry
When it comes to The Cantos, Pound can often seem like a bit of a two-trick pony. In Canto VII, for example, you'll either find him writing in a slow, sad tone or a thumping, angry one. And this all pretty much depends on how much Pound feels like blaming other people for the so-called fall of the modern world.
Earlier in the poem, for example, you get more a sense of Pound's sadness in the sound of lines like, "We also made ghostly visits, and the stair/ That knew us, found us again on the turn of it,/ Knocking at empty rooms, seeking a buried beauty" (28-30). The language is very light and wandering, conveying to us a sense of Pound's own sad search for beauty in a world where the chances for beauty to exist are all but gone.
On the other hand, Pound starts to get angrier as the poem unfolds, and he marks his anger by giving his poem a thumping, even booming sound as his language gets more aggressive. Starting at line 70, for example, Pound blames the problems of the modern world on the "Thin husks I had known as men,/ Dry casques of departed locusts/ speaking a shell of speech…" Later still, he explodes with the line, "The young men, never!", which helps convey just how much dislike Pound has for these old men who close their minds to the ideas of younger, fresher generations. Don't you just hate it when older people are like that?
