During his childhood he learned to play the piano, accordion, violin, oboe, cornet, and later the saxophone. Before World War I, he graduated from the St Petersburg School of Commerce, studied at the Institute of Mountain Engineering, and studied voice at the St Petersburg Conservatory. In 1920 he came to Kaunas, played in the State Theatre Opera Orchestra, sang in the choir and took part in the first production of Traviata. In 1922 he continued his vocal studies at the Leipzig Conservatory. From 1924 he worked at the Liepaja Opera Theatre, creating principal and minor tenor roles. Around 1929 he returned to Kaunas. Until 1933 he worked at the State Opera Theatre. After becoming interested in popular music, he soon became one of the most prominent artists of this genre. He sang in the restaurants Metropolis and Versalis, and in Max Konrad's café. He took part in the first live broadcasts on Lithuanian radio.
He was also active in other activities, having established a milk processing company and a sweet factory
Ada. In the mid-1940s he organised a jazz orchestra and played the saxophone himself. He promoted the then scarce Lithuanian authors Kajetonas Leipaus, Leonards Lechavičius,
S. Gailevičius, N. Naikauskas for the so-called small stage. Among other Lithuanian entertainers, Dvarionas stood out for his impeccable diction, musicality and a sense of the style of entertainment music.
Dvarionas was the director of Kaunas theatre Varjetė during World War II, and took part in its programmes. In 1944 he left for the West. In Copenhagen he directed a Lithuanian choir. In 1948 he settled in Canada, organist and conductor of the Lithuanian choir in Toronto.
