Russian Easter Festival Overture: Overture on Liturgical Themes (Russian: Светлый праздник, Svetliy prazdnik), Op. 36, also known as the Great Russian Easter Overture, is a concert overture written by the Russian composer Nikolai Rimsky-Korsakov between August 1887 and April 1888. It was dedicated to the memories of Modest Mussorgsky and Alexander Borodin, two members of the group of composers known in English as "The Five". It is the last of what many call his three most exceptionally brilliant orchestral works, preceded by Capriccio Espagnol and Scheherazade. The work received its premiere at a Russian symphony concert in St. Petersburg in late December 1888.
The overture is scored for a Romantic orchestra consisting of 3 flutes (1 doubling piccolo), 2 oboes, 2 clarinets in C, 2 bassoons, 4 horns in F, 2 trumpets in B-flat, 3 trombones, tuba, 3 timpani tuned to A, D and G, percussion (glockenspiel, triangle, cymbals, bass drum, tam-tam), harp, and strings.
The score is prefaced by two quotations from the Old and New Testaments and a third written by the composer corresponding to each of the overture's three parts. The first part is prefaced by two verses from Psalm 68:1–2; the second from the Gospel of Mark 16:1–6; and a third which is a description of the Easter celebration written by the composer himself.
