Joaquín Romualdo Gaztambide y Garbayo was one of the most prominent Spanish composers of zarzuela in the mid-nineteenth century. His contribution to the revival of the genre was highly significant; and although during the last century his work virtually disappeared from the Spanish musical scene, the early 21st century has reversed this trend. Of Italianate quality in the manner of Gaetano Donizetti, his music nonetheless makes use of Spanish rhythms and dance forms. Among other renowned works, his La Mensajera (1849), El valle de Andorra (1851), El sueño de una noche de verano, Catalina (1854), Los magiares (1857), El juramento (1858), and the one-act classic Una vieja (1860) stand out.

Zarzuela is a Spanish lyric-dramatic genre that alternates between spoken and sung scenes, the latter incorporating operatic and popular songs, as well as dance. The etymology of the name is uncertain, but some propose it may derive from the name of a royal hunting lodge, the Palace of Zarzuela, near Madrid, where that type of entertainment was allegedly first presented to the court. The palace in turn was named after the brambles that grew there.
