The vidala is a melancholic folk song representative of northwestern Argentina, sung to the rhythm of drums such as the caja and bombo. Conventionally, the drums are played on the first and third beats, and the melody is often sung in two voices, maintaining an interval of a third. As if imitating this performance practice, in Ginastera's version of the vidala, the low notes in the left hand are played in octaves on the first and third beats, and the melody in the right hand emphasizes intervals of a third. Furthermore, the mournful atmosphere of the vidala is conveyed through the chromatic descent, reminiscent of a lament bass, seen in the left hand during the latter half.
