His production amounted to over 500 works, most of them songs for piano and voice, many still unpublished. His style was quite conservative, always tonal and lusciously romantic. His compositions were clearly influenced by Argentine folk music. His reputation was based almost entirely on his songs, and Guastavino has sometimes been called "the Schubert of the Pampas." Some of his songs, for example "Pueblito, mi pueblo", "La rosa y el sauce" ("The Rose and the Willow") and "" ("The Dove Was Wrong"), became national favorites. Unlike most other composers, at any time or place, Guastavino earned enough from his royalties and performing rights that he really had little need for other income.<ref name="BkltNI5818/20">MacDonald, Callum.
