||Snow 1977, no. 169: "This is one of twelve brief articles (all with the same title, apparently) appearing over the course of the year in Radio Nacional. In barely six columns of text, A. manages, persuasively, to support his contention that Alfonso was an accomplished musician and that Fernando III, his father, was also. Alfonso's contemporaries knew this and there was, consequently, much polyphonic interchange between Spain and France, where Alfonso's cousin, Louis, was on the throne. Alfonso endowed a chair of music at Salamanca, one more indication of his interest in music. A. argues - with the musical transcriptions of CSM 361 and 347 - that the texts themselves tend to provide proof of Alfonso's intervention as composer of the pieces."
