A male subject, estimated late 20s to early 30s, with dark, curly hair and a beard, is seated at an upright piano. He wears a brown short-sleeved t-shirt and dark knee-length shorts, occupying a black office-style chair with a chrome base. His torso is angled towards the right, while his head is turned sharply to his left, looking directly at the camera with a slight smile. His right hand rests on the piano's keys. The piano is a dark wooden G. Schwechten Berlin upright model, with its top panel open, revealing the internal gold-colored harp, hammers, and strings. The keyboard features white keys, some appearing discolored, and black keys. A black thermos with a red cap is positioned on top of the piano. Behind the piano, a black and white framed photograph depicting an individual in a hat is mounted on a light grey wall. To the subject's left, partially visible, are a light-colored wooden structure with fabric and a dark, multi-legged stand. The room features a wooden plank floor and an off-white ceiling with exposed electrical conduits. Artificial lighting illuminates the scene, casting subtle shadows. The specific location within Buenos Aires, Argentina, cannot be determined from the visual information provided.
