The title “Música, Instrumentos y Danzas en las Obras de Cervantes,” (Music, Instruments and Dances in the Works of Cervantes) by Adolfo Salazar, [published in two parts in Nueva Revista de Filología Hispánica, Mexico, January to March and April to June, 1948] gives only a hint of the wealth of information and material which the author has brought together on music and musical practices in Spain during the sixteenth and early seventeenth centuries. The discussion also leads to a consideration of the earlier sources and later developments of instruments and musical and dance forms and practices. This brief summary can only indicate the items of most importance for the general history of music.
