While the journal deals with a large number of subjects, its main focus is opera. This is reflected in the publication of biographies of composers, singers and conductors, histories of opera houses, reviews of performances, plot summaries and articles dealing with specific aspects of a work. Despite the continuing popularity of the zarzuela there are strong indications in the journal of a trend favoring the creation of a national Spanish operatic genre. See, for example, Guillermo Morphy's extensive article on the recently-composed opera Maria del Carmen by Enrique Granados. A growing interest in Wagner's operas and ideas is noted in Eduardo Blasco's summaries of Wagner's librettos and reports on performances of Wagner's operas in Spain and abroad.
Many notices report on the musical activities of the principal Spanish cities.
