I once saw - scene at the piano.

Painted in 1884, this interior scene depicting a figure at the piano represents Wyczółkowski's early engagement with bourgeois domestic subjects before his sustained focus on labour and landscape themes. The scene at the piano was a staple of nineteenth-century genre painting across Europe, associated with feminine accomplishment, domestic harmony, and the cultured middle-class interior. Wyczółkowski's early career included a range of such salon subjects, demonstrating his technical versatility and his ability to respond to the market for intimate domestic scenes. The title — which begins "I once saw" — suggests a nostalgic or memory-laden framing, adding a sentimental dimension characteristic of Polish Romantic-inflected genre painting. The work is held in the National Museum in Warsaw.

The composition is organized around the figure at the keyboard, with interior elements — furniture, walls, light sources — framing the central subject. Wyczółkowski employs carefully observed interior light, likely combining natural window light with the warm tones associated with domestic lamplit interiors.
