The Violinist is a sculpture made by Pablo Gargallo in 1920 and currently kept in the National Museum of Art of Catalonia. The work was acquired at the Barcelona "Art Exhibition" of 1920.

Pablo Gargallo created The Violinist by nailing and welding lead sheets on a wooden core. Currently, the surface of the sculpture is deformed with blisters due to the incompatibility between the two materials. The analysis of the white compound that has formed inside some lead sheets has confirmed corrosion due to carbonation, a degradation initiated due to the volatile organic compounds emitted by the wood, which has worsened over the years.

To evaluate the degree of affectation of the lead and understand the interior of the Violinista, he has resorted to a non-destructive technique, capable of penetrating the lead: neutron radiography. The study, pioneering in Spain, was carried out at the Paul Scherrer Institut in Switzerland.[1]​.

With the tomography obtained, it has been possible to know the sculptor's execution technique and maps of alterations have been made, with the location of the affected interior areas. The results have been fundamental to specify what the intervention in the sculpture should be.
