Ars musica (Juan Gil de Zamora)
Open-knowledge reference entry

The Ars musica (or Ars musicae) is a treatise on music theory by Juan Gil de Zamora, a polymath in the literary circle around King Alfonso X of Castile. It has been dated to as early as the 1250s or as late as the period 1296–1304. It is the only surviving work of music theory from medieval Castile.
The Ars musica was written in Latin, which may indicate that Gil intended to reach an international audience. It is dedicated to a certain John, either John of Parma or the Italian Franciscan Giovanni Mincio da Morrovalle. It is divided into a prologue and 17 chapters. The first two chapters deal with the origins of music and its emotional effects. In the following chapter, Gil integrates the ideas of Guido of Arezzo, John of Afflighem and Boethius. The final chapter is devoted to musical instruments, and relies heavily on the work of Bartholomaeus Anglicus. Gil held that of all instruments only the organ was appropriate to church services.
