Adam de la Halle ~ 1250Robin m'aime, Robin loves me,
This is by the celebrated trouvére, Adam dela Halle (trouvéres were from northern France, the better known troubadours from the south), written c.1284. It is from a musical play, Jeu de Robin et de Marion. It is a rondeau, a type of the forme fixe, where the melody and chorus occur in a certain routine.
Besides being a cute melody and very easy to play, the words are fun too.
