What enchants in Provençal poetry and in medieval French fixed forms is above all the melodious sonority, which only occurs because there is an inalienable link with music in both, that is, it only occurs because the compositions, if not intended for singing, are always intended to be recited with musical accompaniment. So rhythm and melody must necessarily harmonize in them as a constructive requirement, having an effect, or rather, endowing the composition with the delicious quality that modern poetry has striven to strip away.
