This research takes as a starting point the Alberto Ginastera's Sonata for Guitar, op. 47 (1976) The Sonata represents, within Ginastera's musical trajectory, an example of synthesis of his work, due to the variety of compositional and motivic material that he manages to link. Its interest relies in the way in which avant-garde compositional techniques, such as serialism or twelve-tone technique, are mixed with folklore rhythms and popular elements typical of Argentine traditional music.
It offers the opportunity to verify in his compositional practice the theoretical approaches on music that the composer had presented in his previous works. Discovering the origin of the thematic and rhythm sources of the Sonata for Guitar by Ginastera is an invitation to inquire in the valuable atmosphere of Argentine folklore.
Since its premiere, the Sonata has attracted increasing interest for its innovative contributions to contemporary music. The result is a tribute to the guitar, the Argentine folk music and the avant-garde music. As far as the guitar as an instrument is concerned, in it the composer explores a great variety of innovative resources that verify its suitability to transmit the contents of contemporary music, while at the same time pays off the debt it had with Argentine folklore, present in its rhetoric and symbolically evoked, but now transfigured into a reality.
Finally, this research presents some connections between this guitar piece and the String Quartet No. 1, op. 20, that Ginastera composed more than twenty years before.
