This page identifies the painting as "The Kreutzer Sonata," by Rene Prinet, from 1898.

There is a very similar painting shown at this Russian site, which also identifies it as "The Kreutzer Sonata," but it doesn't quite match the one in the Tabu ad. Compare, for example, the position of the sheet music, and the woman's hair. Too bad I can't read the Russian (which might be more about Beethoven's 1805 sonata than the painting).
