That meant no interchangeable lines as in troubadour poetry and fewer repetitions: for a French "jongleur" who sang his poems these were necessary, but they sounded redundant to the Sicilian authors. Their poetry was music to the eye, not to the ear, and their legacy is also apparent in Dante and Petrarch's lyrics. The sonnet is even more exacting on this point: the separation between the octave and the sestet is purely a logical one, the rimes drawing a visual line between the first and last part. However, the fact that Italian poetry was being made for the reading public may have facilitated its circulation.
