Elegia (In English: Elegy; occasionally with the Finnish subtitle "Suru ", or "Sadness"), Op.
 4/1, is a composition for string orchestra by the Finnish composer Leevi Madetoja, who wrote the piece in 1909 during his student years.
 On 10 January 1910, Robert Kajanus, chief conductor of the Helsinki Orchestral Society, premiered the "Elegia" to great acclaim, with the piece described as the "first master work" of a budding "natural orchestral composer".
 Madetoja subsequently designated the "Elegia" as the first number in his four-movement "Sinfoninen sarja" ("Symphonic Suite"), Op. 4, which the Helsinki Orchestral Society performed in its entirety under the composer's baton on 26 September 1910.
 The suite's three other numbers are virtually unknown, and the "Elegia" typically is performed as a stand-alone concert piece.
 Stylistically reminiscent of Tchaikovsky, it is, to date, Madetoja's most recorded and well-known orchestral composition, as well as the most enduringly popular of his many miniatures.
The Concerto for Cello, Piano, and String Orchestra is a composition for solo cello, piano, and a large string orchestra by the American composer Ralph Shapey.

 The piece was a finalist for the 1990 Pulitzer Prize for Music and shared the top Kennedy Center Friedheim Award prize with William Kraft for "Veils and Variations for Horn and Orchestra".

Elegiac Ode, Op. 21, is a musical composition by British composer Charles Villiers Stanford (1852–1924) written and first performed in 1884.
 It is a four-movement work scored for baritone and soprano soloists, chorus and orchestra, Stanford's composition is a setting of Walt Whitman' s 1865 elegy, "When Lilacs Last in the Dooryard Bloom'd", mourning the death of American president Abraham Lincoln.
 According to musicologist Jack Sullivan, Stanford's "Elegiac Ode" likely had reached a wider audience during Whitman's lifetime than his poems.

 Though initial critical reception was lukewarm at best, the score soon came to be recognized as a masterpiece.
 The work, which is roughly twelve to fourteen minutes in length, is like a multi-layered symphonic poem for string orchestra, with several prominent themes.
