Music from the Earliest Notations to the Sixteenth Century

The most obvious rhetorical effect—borrowed from the polyphonic madrigal but vastly augmented—
is the textual repetition. Where polyphonic madrig-alists liked to repeat the last line or couplet to make
the final cadence stick, Caccini repeats the last four lines, amounting to more than half the poem. But what
is so rhetorical about literal repetition? Such a thing might sooner pall than enhance expression.
