The Dryad (Dryaden), Op. 45 No. 1, is a tone poem by
Jean Sibelius. He completed it in early 1910 between skiing trips. He conducted the first performance in Kristiania (now Oslo), Norway, on 8 October 1910, together with the premiere of In Memoriam. He arranged it for piano in 1910 (Die Dryade). The piece has been regarded as one of the composer's "shortest and most original orchestral works", as an "impressionist miniature", proceeding from fragments to a "dance-like theme".
The work is scored for piccolo, 2 flutes, 2 oboes, 2 clarinets (in B♭), 2 Bass clarinets (in B♭), 2 bassoons, 4 horns (in F), 3 trumpets (in B♭), 3 trombones, tuba, tambourine, castanets, snare drum、bass drum and strings.
