수수께끼 변주곡 (Enigma Variations, op. 36)

Edward Elgar composed his Variations on an Original Theme, Op. 36, popularly known as the Enigma Variations, between October 1898 and February 1899. It is an orchestral work comprising fourteen variations on an original theme. After its 1899 premiere in London, the variations quickly achieved popularity and helped establish Elgar's growing reputation in Britain and internationally. It is now a staple of the orchestral repertoire globally. Elgar dedicated the work "to my friends pictured within", each variation being a musical sketch of – or a musical idea related to – one of his circle. Those musically sketched include Elgar's wife Alice, his friend and publisher August Jaeger and, in the final variation, Elgar himself. In addition to the miniature depictions of his friends, Elgar said that the main theme, which he called "Enigma", referred in some way to a larger, unspecified theme. By doing so he posed a challenge that has generated much speculation but has never been conclusively answered. The Enigma theme is widely believed to involve a hidden melody, although some commentators have taken it to represent an abstract idea rather than a musical theme.
