In 1946, Mariss's father, Arvīds Jansons won second prize in a national competition and was chosen by Yevgeny Mravinsky to be his assistant at the Leningrad Philharmonic. When his family joined him in 1956, young Mariss entered the Leningrad Conservatory, where he studied piano and conducting, although his father urged him to continue playing violin. In 1969, he continued his training in Vienna with Hans Swarowsky and in Salzburg with Herbert von Karajan.
