Evoked through a subtle stuttering brush, ‘Girl at Piano’, presents a scene as simple as its title. The child herself seems relaxed in repose rather than a player, both her folded hands and absent face realized in the most minute of movements. Similarly to Krzyzanowski's painting Chmury, a sense of size is conveyed expertly. A piano is of course a huge instrument, but one that to a child especially conveys a gigantic almost monstrous nature. There is a feeling of abstraction here then, that these two things belong to the same world but exist entirely apart from one another. Both the girl and the piano are ignored, resigned to merely waiting for something to happen.
