A troubadour sits on an old staircase of a castle and plays his “Lied ohne Worte” lost in thought. Italian-looking buildings as a backdrop. Hartmann himself painted a medieval tower (he had studied architecture in Italy).

Pictures at an exhibition by Modest Moessorgski
It is a ten-part suite by Modest Musorgsky (1874) a Russian composer. Inspired by paintings by his friend the painter Viktor Hartman. I painted my version. These were projected through a keynote presentation by Jan Penninkhof while the suite was played by colleague Gerard van der Laan (pianist).
