||Snow 2007: "There are echoes of the zéjel, and of the cantares de gesta (in cantigas 296, 27, 73, and 120). The music of the CSM is monodic, with a central emphasis on the virelai forms (influence is seen from France and Provence, as that established for 340 and Cadenet's alba, "S'an fuy bela"). Posits that the simpler cantigas had popular melodies, while those with universalist or historical themes had more complicated melodies. The participation of Jews and Arabs was, probably, as accompanists only. Its advanced mensural notation distinguishes the CSM from other European monodic music and Anglés gets high marks for the musical transcriptions he made of the CSM. Many color illustrations from CSM miniatures."
