He studied piano with H. Hansen, Dagmar Walle-Hansen, Inge Rolf Ringnes, Karl Leimer, Reimar Riefling, Nils Larsen, Aleksander Borovsky and Edwin Fischer and theory with Fartein Valen. In 1942 Wølner refused the order of Edvard Sylou-Creutz, pianist and head of the music department of the National Radio, to join the official NS-musicians’ association. Therefore, Sylou-Creutz called for a ban against him, Robert Riefling, Fridtjof Backer-Grøndahl, Amalie Christie, Rolf Størseth and Kari Glaser to perform in the University Hall.
