||Snow 1977, no. 158: "There are references passim to the CSM, some quite interesting. Shows the virelai forms present in Latin verse prior to Alfonso (p. 256). Confirms Spanke's opinion that CSM 279 is a modified rondeau (p. 343). Theorizes about the CSM's influence on the Catalan troubadour Cerverí (p. 343). Discusses how it may be shown - with CSM 12 as an example - that mixed modal rhythm was already developed in the Peninsula (pp. 352-3). Notes similarities to the CSM in a song by Arnaut de Marueill, ca 1170-1200 (p. 394)."
