Today, three versions of the work survive. Initially in 1913, Sibelius conceived of the commission as a three-movement suite for orchestra in E major, of which only No. 2 ("Tempo moderato") and No. 3 ("Allegro") are extant. At some point in 1913–14, Sibelius decided to rework the thematic material of the "Allegro", very much a "work in progress", into a single-movement symphonic poem; the musical content of the "Tempo moderato" would find its way into the piano piece "" ("To Longing"), JS 202. In making the transition from suite to tone poem, Sibelius transposed the material from E to D major; in addition, he also introduced new musical ideas, such as the rocking wave-like motif in the strings and woodwinds, and expanded the orchestration.
