"The Wood Nymph", a single-movement tone poem for orchestra, was written in 1894. Premiered in April 1895 in Helsinki with Sibelius conducting, it is inspired by the Swedish poet Viktor Rydberg's work of the same name. Organizationally, it consists of four informal sections, each corresponding to one of the poem's four stanzas and evoking the mood of a particular episode: first, heroic vigour; second, frenetic activity; third, sensual love; and fourth, inconsolable grief. Despite the music's beauty, many critics have faulted Sibelius for his "over-reliance" on the source material's narrative structure.
