Marguerite Gachet at the Piano was painted by Vincent van Gogh in 1890. Dr. Gachet reciprocated Vincent's open friendship, welcoming van Gogh into his home for lively discussions and allowing his daughter to pose for several portraits. In Marguerite Gachet at the Piano, Vincent van Gogh employs a combination of brush strokes -- long free strokes on the piano, Neo-Impressionist dabs on the wall, thick repetitive strokes on her gown -- to create a decorative surface, as if sculpted in impasto.
Despite the seeming return to good health, all was not well with Vincent van Gogh. This emerged in his art, as in the next painting you'll see.
