The special kind of musicology practised by the priest Monsignor Higini Angles inhabits a rigorous scientific domain. His publications, issued by the Music Department of the Library of Catalonia, are invaluable contributions on account of their knowledge of Hispanic musical culture. The music at the court of Alfonso the Magnanimous has become an exceptionally interesting subject both for its content and because all accounts by Mgr Angles are a result of personal direct research, much of it unpublished. The archives of the Cancilleria de Barcelona are immensely rich in historic documentation on the music and the musicians encountered at the royal court of Catalonia-Arago during the late fourteenth and first half of the fifteenth century. The precedents for love music at the court of Castile of the end of the fifteenth century can already in fact be found at Alfonso’s court.
