Five multi-movement trios for piano and two string instruments by Sibelius are known from the years 1883–1888. The “large” trios, such as the Havträsk and Korpo Trio (JS 207, JS 209), were written for the classical piano trio scoring of violin, violoncello and piano. Apparently, Sibelius kept composing trios to play among his family and friends, having in mind to be one of the musicians himself. Chamber music was an essential part of social life. When listening to Sibelius‘ trios, one cannot help but notice that the repertoire included many works of Viennese Classicism.

Although Sibelius's feelings towards his youthful works were not exactly uncomplicated, Sibelius biographer Otto Andersson later reported “that the master, in later years, missed [the Korpo Trio] very much and would have been very pleased to see [it] preserved.”
