A violin concerto is a concerto for solo violin (occasionally, two or more violins) and instrumental ensemble, customarily orchestra. Such works have been written since the Baroque period, when the solo concerto form was first developed, up through the present day. Many major composers have contributed to the violin concerto repertoire, with the best known works including those by Bach, Bartók, Beethoven, Brahms, Bruch, Mendelssohn, Mozart, Paganini, Prokofiev, Shostakovich, Sibelius, Tchaikovsky, and Vivaldi.
Swan Lake, Op. 20, is a ballet composed by Pyotr Ilyich Tchaikovsky in 1875–76. Despite its initial failure, it is now one of the most popular of all ballets. The scenario, initially in two acts, was fashioned from Russian folk tales[a] and tells the story of Odette, a princess turned into a swan by an evil sorcerer’s curse.
