Enigma variations, Op. 36 Edward Elgar composed his Variations on an Original Theme for Orchestra ("Enigma"), Op. 36, commonly referred to as the Enigma Variations, in 1898–99. It is a set of fourteen variations on a hidden "theme" that is, in Elgar's words, "not played". It is Elgar's best-known large-scale composition, for both the music itself and the enigma behind it. Elgar dedicated the piece to "my friends pictured within", each variation being an affectionate portrayal of one of his circle of close acquaintances. The people portrayed in the variations include Elgar's wife Alice, Augustus J. Jaeger and Elgar himself. The enigma is the hidden theme, which has been the subject of much speculation. Various musicians have proposed theories for what melody it could be, although Elgar did not say that that his "theme" was a melody. The enigma could be something else, such as a symbol or a literary theme. Elgar accepted none of the solutions proposed in his lifetime, and took the secret with him to the grave. After its 1899 London premiere, the piece achieved popularity and was performed internationally. Sir Edward William Elgar was an English composer, many of whose works have entered the British and international classical concert repertoire. Among his best-known compositions are orchestral works including the Enigma Variations, the Pomp and Circumstance Marches, concertos for violin and cello, and two symphonies. He also composed choral works, including The Dream of Gerontius, chamber music and songs. He was appointed Master of the King's Musick in 1924. Although Elgar is often regarded as a typically English composer, most of his musical influences were not from England but from continental Europe. He felt himself to be an outsider, not only musically, but socially. In musical circles dominated by academics, he was a self-taught composer; in Protestant Britain, his Roman Catholicism was regarded with suspicion in some quarters; and in the class-conscious society of Victorian and Edwardian Britain.
