Although he is known as one of the most important Argentine plastic artists, Xul Solar (1887-1963) displayed his creativity not exclusively through painting, but also working and deepening in numerous scientific disciplines, esoteric knowledge and artistic domains, among which music occupied a privileged place. This was a constant company throughout his life. From a young age he became interested in his studio and, as an artist, he experimented with the design of original instruments and systems of musical notation. However, music was not simply a parallel vocation in Xul but it was such a strong conceptual and iconographic influence on her pictorial work that the author of this book does not consider the artist as a painter interested in music, but as a "Visual musician". Musicologist Cintia Cristiá has dealt with the multiple interrelationships between music and life and the work of Xul Solar. An article of his on this subject was awarded at the 1st International Gourmet Musical Research Contest on Latin American Music (2003), while his contribution to the catalog of the exhibition dedicated to this artist at MALBA (2005) received the Eleonora Traficante Award to the essay of the year, within the framework of the 2005 Critics Awards presented by the Argentine Association of Art Critics.
