Unlike the eminent Nordic composers Edward Grieg, Jean Sibelius, and Carl Nielsen, Swedish composer Wilhelm Stenhammar (1871-1927) and his compositions have been long forgotten. However, the composer and his works are gradually being recognized through an increase in performances, recordings, and research. This paper discusses Stenhammar's three early chamber works for piano and strings, Allegro brillante for Piano Quartet in E-flat Major (1891), Allegro non tanto for Piano Trio in A Major (1895), and Sonata for Violin and Piano in A Minor, op. 19 (1899-1990) in search of the elements of German Classicism, German Romanticism, and Swedish Nationalism, that define his mature style. Although these works might be considered to be juvenilia lacking any of Stenhammar's distinguishing color, these three early chamber works are stepping stones to the musical traits that characterize his later mature works.
