An influential figure in the Lithuanian music of the early 20th century, composer, choir leader and singer Mikas Petrauskas (1873-1937) was a musician of wide-ranging interests and a trailblazer of many new undertakings in Lithuanian music life. In Lithuanian music history, however, he is mostly credited as an author of the first Lithuanian opera, "Birutė". Though not greatly varied in genre, Mikas Petrauskas' list of works numbers quite a sizable oeuvre which falls into two major categories - works for stage and voice.
