Jean Sibelius Tapiola, Op112: Tone Poem for Large Orchestra. The symphonic poem Tapiola is the final major composition for orchestra that Sibelius was able to complete and publish. In January 1926 he had accepted the commission from the conductor Walter Damrosch to compose an orchestral work of at most 20 minutes in length for a performance in New York at the end of that year. Shortly thereafter Sibelius was successful in getting Breitkopf & Härtel to do the first publication of this tone poem.
