The title of this tango always arouses curiosity, adding to the beauty of listening to it as the incredible creation that Carlos Di Sarli made of it, recording it on April 18, 1941.
This composition belongs to Martín Lasala Álvarez, an Uruguayan doctor who was a functionary of the Uruguayan state for most of his life, working for the Foreign Service of Uruguay in Paris.
The word "estagiario" does not exist either in the Lunfardo or in the popular jargon of the Oriental people (the people of República Oriental del Uruguay). Instead, it is an adaptation of Lasala himself - from the French "stagiare", the practitioner or advanced medical student who collaborates in the Hospital's practices.
Martín Lasala, who completed studies in Paris, was also a piano performer. But, to mitigate nostalgia or to animate meetings, as a good Rio Platense, he gave free rein to his passion, playing and composing tangos.
Carlos Di Sarli was the one who captured and recorded the richness of this tango.
