Bergman studied in the Helsinki Conservatory, with Tiessen on the Hochschule für Musik and studied serialism with Vogel in Ascona. He empty romanticism and only serialism in the afterwards 1940s. He uses it as a way with which to regulate intervallic colour instead of being a thematic concept. Bergman composed many choral functions. He employs methods such as for example Sprechgesang and talk, sometimes for your piece. In his afterwards works Bergman followed an improvisatory, aleotory technique in rigorous form.
