Rimas Dissolutas is a troubaderic verse form in which verses rhyme with each other instead of having the lines of each verse rhyme internally. A poem in quatrains would have a rhyme scheme of ABCD ABCD, etc. Lines can be of any length but are generally isosyllabic while verses can be any number of lines.
The chanso is a poem and song form (lyrical verse) that was popular among the troubadours in medieval France due to its variable-length stanzas and metrical consistency from verse to verse. While the form hasn’t seen much success in English, some cansos remain famous in France well into the modern day.
