This form is like a pizza with the crust folded over the
top to make a shell...oh, uh, what a difference one letter can make.
The Canzone is an Italian poetic form usually using seven or eleven syllable lines with three major divisions or movements. Within each movement there are
three stanzas, the first two alike and the third of a different structure. (Much like the Pindaric ode.) The poem usually closes with a commiato or
valediction.
There is no set structure for the stanzas, just the pattern of similarity and dissimilarity between the stanzas. |
