Edward Elgar composed his Variations, 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.
Elgar dedicated the work 'to my friends pictured within', each variation being a musical sketch of one of his circle of close acquaintances (see musical cryptogram). Those portrayed include Elgar's wife Alice, his friend and publisher Augustus J. Jaeger and Elgar himself. In a programme note for a performance in 1911 Elgar wrote:
This work, commenced in a spirit of humour & continued in deep seriousness, contains sketches of the composer’s friends. It may be understood that these personages comment or reflect on the original theme & each one attempts a solution of the Enigma, for so the theme is called. The sketches are not ‘portraits’ but each variation contains a distinct idea founded on some particular personality or perhaps on some incident known only to two people. This is the basis of the composition, but the work may be listened to as a ‘piece of music’ apart from any extraneous consideration. 
In naming his theme ‘Enigma’ Elgar posed a challenge which has generated much speculation but has never been conclusively answered. The Enigma is widely believed to involve a hidden melody.
After its 1899 London premiere the Variations achieved immediate popularity and established Elgar's international reputation. The work has been recorded over 60 times.

Elgar described how on the evening of 21 October 1898, after a tiring day's teaching, he sat down at the piano. A melody he played caught the attention of his wife, and he began to improvise variations on it in styles which reflected the character of some of his friends. These improvisations, expanded and orchestrated, became the Enigma Variations. Elgar considered including variations portraying Arthur Sullivan and Hubert Parry, but was unable to assimilate their musical styles without pastiche, and dropped the idea.
The piece was finished on 18 February 1899 and published by Novello & Co. It was first performed at St James's Hall in London on 19 June 1899, conducted by Hans Richter. Critics were at first irritated by the layer of mystification, but most praised the substance, structure, and orchestration of the work. Elgar later revised the final variation, adding 96 new bars and an organ part. The new version, the one usually played today, was first heard at the Worcester Three Choirs Festival on 13 September 1899, with Elgar conducting.
The European continental premiere was performed in Düsseldorf, Germany on 7 February 1901, under Julius Buths (who would also conduct the European premiere of The Dream of Gerontius in December 1901). The work quickly achieved many international performances, from Saint Petersburg, where it delighted Alexander Glazunov and Nikolai Rimsky-Korsakov in 1904, to New York, where Gustav Mahler conducted it in 1910.
The work is scored for an orchestra consisting of 2 flutes (one doubling piccolo), 2 oboes, 2 clarinets in B flat, 2 bassoons, contrabassoon, 4 horns in F, 3 trumpets in F, 3 trombones, tuba, timpani, side drum, triangle, bass drum, cymbals, organ (ad lib) and strings.
The theme is followed by 14 variations. The variations spring from the theme's melodic, harmonic and rhythmic elements, and the extended fourteenth variation forms a grand finale.
Elgar dedicated the piece to 'my friends pictured within' and in the score each variation is prefaced the initials, name or nickname of the friend depicted. As was common with painted portraits of the time, Elgar's musical portraits depict their subjects at two levels. Each movement conveys a general impression of its subject's personality. In addition, many of them contain a musical reference to a specific characteristic or event, such as a laugh, a habit of speech or a memorable conversation. The sections of the work are as follows.
Theme (Enigma: Andante)
The unusual melodic contours of the G minor opening theme convey a sense of searching introspection:
A switch to the major key introduces a flowing motif which briefly lightens the mood before the first theme returns, now accompanied by a sustained bass line and emotionally charged counterpoints.
In a programme note for a 1912 performance of his setting of Arthur O’Shaughnessy’s ode The Music Makers Elgar wrote of this theme (which he quoted in the later work), 'it expressed when written (in 1898) my sense of the loneliness of the artist as described in the first six lines of the Ode, and to me, it still embodies that sense'.
Elgar’s personal identification with the theme is evidenced by his use of its opening phrase (which matches the rhythm and inflection of his name) as a signature in letters to friends.
The theme leads into Variation I without a pause.
Variation I (L'istesso tempo) 'C.A.E.'
Caroline Alice Elgar, Elgar's wife. The variation repeats a four-note melodic fragment which Elgar reportedly whistled when arriving home to his wife. After Alice's death, Elgar wrote, 'The variation is really a prolongation of the theme with what I wished to be romantic and delicate additions; those who knew C.A.E. will understand this reference to one whose life was a romantic and delicate inspiration'.
(In these notes Elgar’s words are quoted from his posthumous publication My Friends Pictured Within which draws on the notes he provided for the Aeolian Company's 1929 pianola rolls edition of the Variations.)
Variation II (Allegro) 'H.D.S-P.'
Hew David Steuart-Powell. Elgar wrote, 'Hew David Steuart-Powell was a well-known amateur pianist and a great player of chamber music. He was associated with B.G.N. (cello) and the composer (violin) for many years in this playing. His characteristic diatonic run over the keys before beginning to play is here humorously travestied in the semiquaver passages; these should suggest a Toccata, but chromatic beyond H.D.S-P.'s liking'.
Variation III (Allegretto) 'R.B.T.'
Richard Baxter Townshend, Oxford don and author of the Tenderfoot series of books; brother-in-law of the W.M.B. depicted in Variation IV. This variation references R.B.T's presentation of an old man in some amateur theatricals ‒ the low voice flying off occasionally into 'soprano' timbre.
Variation IV (Allegro di molto) 'W.M.B.'
William Meath Baker, squire of Hasfield, Gloucestershire and benefactor of several public buildings in Fenton, Stoke-on-Trent, brother-in-law of R.B.T. depicted in Variation III, and (step) uncle of Dora Penny in Variation X. He 'expressed himself somewhat energetically'. This is the shortest of the variations.
Variation V (Moderato) 'R.P.A.'
Richard Penrose Arnold, the son of the poet Matthew Arnold, and an amateur pianist. This variation leads into the next without pause.
Variation VI (Andantino) 'Ysobel'
Isabel Fitton, a viola pupil of Elgar. Elgar explained, 'It may be noticed that the opening bar, a phrase made use of throughout the variation, is an ‘exercise’ for crossing the strings – a difficulty for beginners; on this is built a pensive and, for a moment, romantic movement'.
Variation VII (Presto) 'Troyte'
Arthur Troyte Griffith, a Malvern architect and one of Elgar's firmest friends. The variation good-naturedly mimics his enthusiastic incompetence on the piano. It may also refer to an occasion when Griffith and Elgar were out walking and got caught in a thunderstorm. The pair took refuge in the house of Winifred and Florence Norbury (Sherridge, Leigh Sinton, near Malvern), to which the next variation refers.
Variation VIII (Allegretto) 'W.N.'
Winifred Norbury, one of the secretaries of the Worcester Philharmonic Society. 'Really suggested by an eighteenth-century house. The gracious personalities of the ladies are sedately shown. W.N. was more connected with the music than others of the family, and her initials head the movement; to justify this position a little suggestion of a characteristic laugh is given.'
This variation is linked to the next by a single note held by the first violins.
Variation IX (Adagio) 'Nimrod'
Augustus J. Jaeger was employed as music editor by the London publisher Novello & Co. He was a close friend of Elgar, giving him useful advice but also severe criticism, something Elgar greatly appreciated. Elgar later related how Jaeger had encouraged him as an artist and had stimulated him to continue composing despite setbacks. The name of the variation refers to Nimrod, an Old Testament patriarch described as 'a mighty hunter before the Lord' – Jäger being German for hunter.
In 1904 Elgar told Dora Penny ('Dorabella') that this variation is not really a portrait, but 'the story of something that happened'. Once, when Elgar had been very depressed and was about to give it all up and write no more music, Jaeger had visited him and encouraged him to continue composing. He referred to Ludwig van Beethoven, who had a lot of worries, but wrote more and more beautiful music. "And that is what you must do", Jaeger said and he sang the theme of the second movement of Beethoven's Piano Sonata No. 8 Pathétique. Elgar disclosed to Dora that the opening bars of 'Nimrod' were made to suggest that theme. "Can’t you hear it at the beginning? Only a hint, not a quotation."
This variation has become popular in its own right and is sometimes used at British funerals, memorial services, and other solemn occasions. It is always played at the Cenotaph, Whitehall in London on Remembrance Sunday. A version was also played during the Hong Kong handover ceremony in 1997 and at the opening ceremony of the London 2012 Olympic Games. Musicologist Bill McGlaughlin likens its place in British music to the place Samuel Barber's Adagio for Strings holds for Americans. It was also the last piece ever played by the Greek Symphonical Orchestra (besides the Greek National Anthem) when it closed down in June 2013.[better source needed]
Variation X (Intermezzo: Allegretto) 'Dorabella'
Dora Penny, a friend whose stutter is gently parodied by the woodwinds. Dora, later Mrs. Richard Powell, was the daughter of the Revd (later Canon) Alfred Penny. Her stepmother was the sister of William Meath Baker, the subject of Variation IV. She was the recipient of another of Elgar's enigmas, the so-called Dorabella Cipher. She described the 'Friends Pictured Within' and 'The Enigma' in two chapters of her book Edward Elgar, Memories of a Variation. This variation features a melody for solo viola.
Variation XI (Allegro di molto) 'G.R.S.'
George Robertson Sinclair, the energetic organist of Hereford Cathedral. In the words of Elgar: 'The variation, however, has nothing to do with organs or cathedrals, or, except remotely, with G.R.S. The first few bars were suggested by his great bulldog, Dan (a well-known character) falling down the steep bank into the River Wye (bar 1); his paddling upstream to find a landing place (bars 2 and 3); and his rejoicing bark on landing (second half of bar 5). G.R.S. said, "Set that to music". I did; here it is.'
Variation XII (Andante) 'B.G.N.'
Basil G. Nevinson, an accomplished amateur cellist who played chamber music with Elgar. The variation is introduced and concluded by a solo cello. This variation leads into the next without pause.
Variation XIII (Romanza: Moderato) ' * * * '
Lady Mary Lygon of Madresfield Court near Malvern, a sponsor of a local music festival. 'The asterisks take the place of the name of a lady who was, at the time of the composition, on a sea voyage. The drums suggest the distant throb of the engines of a liner, over which the clarinet quotes a phrase from Mendelssohn’s Calm Sea and Prosperous Voyage.'
Elgar may have withheld Lady Mary’s initials because of superstition surrounding the number 13, or he may felt uneasy about publicly associating the name of a prominent local figure with music that had taken on a powerful emotional intensity. There is credible evidence to support the view that the variation’s atmosphere of brooding melancholy and its subtitle ‘Romanza’ are tokens of a covert tribute to another woman, the name most frequently mentioned in this connection being that of Helen Weaver, who had broken off her engagement to Elgar in 1884 before sailing out of his life forever aboard a ship bound for New Zealand.
Variation XIV (Finale: Allegro) 'E.D.U.'
Elgar himself, nicknamed Edu by his wife, from the German Eduard. The themes from two variations are echoed: 'Nimrod' and 'C.A.E.', referring to Jaeger and Elgar´s wife Alice, 'two great influences on the life and art of the composer', as Elgar wrote in 1927. Elgar called these references 'entirely fitting to the intention of the piece'.
The original version of this variation is nearly 100 bars shorter than the one now usually played. In July 1899, one month after the original version was finished Jaeger urged Elgar to make the variation a little longer. After some cajoling Elgar agreed, and also added an organ part. The new version was played for the first time at the Worcester Three Choirs Festival, with Elgar himself conducting, on 13 September 1899.
Arrangements of the Variations include:
- The composer's arrangement of the complete work for piano solo
- The composer's arrangement of the complete work for piano duet (two pianos)
- Duet (piano, four hands) – by John E. West F.R.A.M., F.R.C.O (1863–1929), organist, composer and musical adviser to Novello's
- Brass band – by composer Eric Ball
- There are many arrangements of individual variations, particularly Variation IX 'Nimrod'

The word ‘Enigma’, serving as a title for the theme of the Variations, was added to the score at a late stage, after the manuscript had been delivered to the publisher. Despite a series of hints provided by Elgar, the precise nature of the implied puzzle remains unknown.
Confirmation that Enigma is the name of the theme is provided by Elgar’s 1911 programme note ('... Enigma, for so the theme is called') and in a letter to Jaeger dated 30 June 1899 he associates this name specifically with what he calls the ‘principal motive’ – the G minor theme heard in the work’s opening bars, which (perhaps significantly) is terminated by a double bar. Whatever the nature of the attendant puzzle, it is likely to be closely connected with this ‘Enigma theme’.
Elgar’s first public pronouncement on the Enigma appeared in Charles A. Barry’s programme note for the first performance of the Variations:
The Enigma I will not explain – its 'dark saying' must be left unguessed, and I warn you that the connexion between the Variations and the Theme is often of the slightest texture; further, through and over the whole set another and larger theme 'goes', but is not played . . . . So the principal Theme never appears, even as in some late dramas – eg Maeterlinck’s L’Intruse and Les sept Princesses – the chief character is never on the stage.
Far from clarifying matters, this utterance seems to envelop the Enigma in further mysteries. The phrase ‘dark saying’ can be read straightforwardly as an archaic synonym for enigma but might equally plausibly be interpreted as a cryptic clue, while the word ‘further’ seems to suggest that the ‘larger theme’ is distinct from the Enigma, forming a separate component of the puzzle.
Elgar provided another clue in an interview he gave in October 1900 to the editor of the Musical Times, F. G. Edwards, who reported:
Mr Elgar tells us that the heading Enigma is justified by the fact that it is possible to add another phrase, which is quite familiar, above the original theme that he has written. What that theme is no one knows except the composer. Thereby hangs the Enigma.
Five years later, Robert Buckley stated in his biography of Elgar (written with the composer’s close cooperation):
The theme is a counterpoint on some well-known melody which is never heard.
It should be noted that Buckley did not quote Elgar saying this or state that Elgar told him so.
Attempted solutions to the Enigma commonly propose a well-known melody which is claimed to be either a counterpoint to Elgar’s theme or in some other way linked to it. Musical solutions of this sort are supported by Dora Penny and Carice Elgar’s testimony that the solution was generally understood to involve a tune, and by the evidence from an anecdote describing how Elgar encoded the solution in a numbered sequence of piano keys. A rival school of thought holds that the ‘larger theme’ which ‘goes’ ‘through and over the whole set’ is an abstract idea rather than a musical theme. The interpretation placed on the ‘larger theme’ forms the basis of the grouping of solutions in the summary that follows.
Julian Rushton has suggested that any solution should satisfy five criteria: a 'dark saying' must be involved; the theme 'is not played'; the theme should be 'well known' (as Elgar stated multiple times); it should explain Elgar's remark that Dora Penny should have been, 'of all people' the one to solve the Enigma; and fifthly, some musical observations in the notes Elgar provided to accompany the pianola roll edition may be part of the solution. Furthermore, the solution (if it exists) ‘must be multivalent, must deal with musical as well as cryptographic issues, must produce workable counterpoint within Elgar’s stylistic range, and must at the same time seem obvious (and not just to its begetter)’.
Elgar accepted none of the solutions proposed in his lifetime, and took the secret with him to the grave.
The prospect of gaining new insights into Elgar’s character and composition methods, and perhaps revealing new music, continues to motivate the search for a definitive solution. But Norman Del Mar expressed the view that 'there would be considerable loss if the solution were to be found, much of the work's attraction lying in the impenetrability of the riddle itself', and that interest in the work would not be as strong had the Enigma been solved during Elgar's lifetime.
Solutions in this category suggest a well-known tune which (in the proponent's view) forms a counterpoint to the theme of the Variations.
After Elgar’s death in 1934 Richard Powell (husband of Dorabella) published a solution proposing Auld Lang Syne as the countermelody. This theory has been elaborated by Roger Fiske, Eric Sams and Derek Hudson. Elgar himself, however, is on record as stating ‘Auld Lang Syne won't do’.
A competition organized by the American magazine The Saturday Review in 1953 yielded one proposed counterpoint – the aria Una bella serenata from Mozart’s Così fan tutte (transposed to the minor key).
In 1993 Brian Trowell, surmising that Elgar conceived the theme in E minor, proposed a simple counterpoint consisting of repeated semibreve E’s doubled at the octave – a device occasionally used by Elgar as a signature.
In 1999 Julian Rushton reviewed solutions based on counterpoints with melodies including Home, Sweet Home, Loch Lomond, a theme from Brahms’s fourth symphony, the Meditation from Elgar’s oratorio The Light of Life and God Save the Queen – the last being Troyte Griffith’s suggestion from 1924, which Elgar had dismissed with the words “Of course not, but it is so well-known that it is extraordinary no-one has found it”.
A few more solutions of this type have been published in recent years. In the following three examples the counterpoints involve complete renditions of both the Enigma theme and the proposed ‘larger theme’, and the associated texts have obvious ‘dark’ connotations.
Tallis’s canon, the tune for the hymn Glory to Thee, my God, this night, features as a cantus firmus in a solution which interprets the Enigma as a puzzle canon. This reading is suggested by the words ‘for fuga’ which appear among Elgar’s annotations to his sketch of the theme.
Hans Westgeest has argued that the real theme of the work consists of only nine notes: G - E flat - A flat - F - B flat - F - F - A flat - G (which are identical to the first nine notes of Nimrod). The rhythm of this theme (in 4/4 time, with a crotchet rest on the first beat of each bar) is based on the rhythm of Edward Elgar's own name ("Edward Elgar": short-short-long-long, then reversed long-long-short-short and a final note). Elgar meaningfully composed this "Elgar theme" as a countermelody to the beginning of the hidden "principal Theme" of the piece, the theme of the slow movement of Beethoven's Pathétique sonata (transposed to E flat). When the two themes are combined each note of the first part of the Beethoven theme is followed by the same note in the Elgar theme. So Elgar “follows” Beethoven, as Jaeger told him to do (see above, Var. IX). The minor melody of the beginning, the variations and the Finale are all based on this "Elgar theme".
Other musical themes
If Robert Buckley’s statement about the theme being ‘a counterpoint to some well-known melody’ is disregarded or discounted the field opens up to admit other kinds of connection with well-known themes.
Entries in this category submitted to the Saturday Review competition included the suggestions When I am laid in earth from Purcell’s Dido and Aeneas, the Agnus Dei from Bach's Mass in B minor, the song None shall part us from Iolanthe and the theme from the slow movement of Beethoven's Pathétique sonata. Elgar himself affirmed that this Beethoven theme is alluded to in variation IX.
In 1985 Marshall Portnoy suggested that the key to the Enigma is Bach's The Art of Fugue. Contrapunctus XIV of that work contains the B A C H motif (in English notation, B♭ A C B♮) which, in Portnoy’s view, can also be found in the Variations.
Theodore van Houten proposed Rule, Britannia! as the hidden melody on the strength of a resemblance between one of its phrases and the opening of the Enigma theme. The word which is sung to this phrase – a thrice-repeated ‘never’– appears twice in Elgar’s programme note, and the figure of Britannia on the penny coin provides a link with Dora Penny. The hypothesis has been further elaborated by van Houten and others, and its credibility has received a boost from a report that it was endorsed by Elgar himself.
Other tunes which have been suggested on the basis of a postulated melodic or harmonic connection to Elgar's theme include Chopin's Nocturne in G minor, John Dunstable's Ave Maris Stella, the Benedictus from Stanford's Requiem , Pop Goes the Weasel, Brahms's "Four Serious Songs", William Boyce's Heart of Oak (transposed to the minor), the Dies Irae plainchant and Gounod's March to Calvary.
Ian Parrott wrote in his book on Elgar that the ‘dark saying’, and possibly the whole of the Enigma, had a biblical source, 1 Corinthians 13:12, which in the Authorised Version reads, ‘For now we see through a glass, darkly (enigmate in the Latin of the Vulgate); but then face to face: now I know in part; but then shall I know even as also I am known.’ The verse is from St. Paul's essay on love. Elgar was a practising Roman Catholic and on 12 February 1899, eight days before the completion of the Variations, he attended a Mass at which this verse was read.
Andrew Moodie, casting doubt on the idea of a hidden melody, postulated that Elgar constructed the Enigma theme using a cipher based on the name of his daughter, Carice.
In 2010 Charles and Matthew Santa have argued that the enigma was based on Pi, following the misguided attempt by the Indiana House of Representatives to legislate the value of Pi in 1897. Elgar created an original melody containing three references to Pi based on this humorous incident. The first four notes are scale degree 3-1-4-2, decimal Pi, and fractional Pi is hidden in the "two drops of a seventh" following the first 11 notes leading to 2/7 x 11 = 22/7, fractional Pi. His "dark saying" is a pun set off by an unexplained double bar after the first 24 notes (all black notes)..."Four and twenty blackbirds baked in a pie (Pi)." Shortly before his death, Elgar wrote three sentences about the variations and each sentence contains a hint at Pi, confirming that Pi is the solution to his enigma. 
Elgar himself quoted many of his own works, including 'Nimrod' (Variation IX), in his choral piece of 1912, The Music Makers. On 24 May 1912 Elgar conducted a performance of the Variations at a Memorial Concert in aid of the family survivors of musicians who had been lost in the Titanic disaster.
Frederick Ashton's ballet Enigma Variations (My Friends Pictured Within) is choreographed to Elgar's score with the exception of the finale, which uses Elgar's original shorter ending (see above), transcribed from the manuscript by John Lanchbery. The ballet, which depicts the friends and Elgar as he awaits Richter's decision about conducting the premiere, received its first performance on 25 October 1968 at the Royal Opera House, Covent Garden, London.
The acclaimed 1974 television play Penda's Fen includes a scene where the young protagonist has a vision of an aged Elgar who whispers to him the "solution" to the Enigma, occasioning astonishment on the face of the recipient. A solution to the Enigma also features in Peter Sutton’s 2007 play Elgar and Alice.
Elgar suggested that in case the Variations were to be a ballet the Enigma would have to be represented by 'a veiled dancer'. Elgar's remark suggested that the Enigma in fact pictured 'a friend', just like the variations. His use of the word 'veiled' possibly indicates that it was a female character.
The Enigma Variations inspired a drama in the form of a dialogue – original title Variations Énigmatiques (1996) – by the French dramatist Eric-Emmanuel Schmitt.
There have been more than sixty recordings of the Variations since Elgar's first recording, made by the acoustic process in 1924. Elgar himself conducted the Royal Albert Hall Orchestra for its first electrical recording in 1926 on the HMV label. That recording has been remastered for compact disc; the EMI CD couples it with Elgar's Violin Concerto conducted by the composer with Yehudi Menuhin as the soloist. Sixty years later, Menuhin took the baton to conduct the Royal Philharmonic Orchestra in the Variations for Philips, as a coupling to the Cello Concerto with Julian Lloyd Webber. Other conductors who have recorded the work include Arturo Toscanini, Daniel Barenboim, Sir Georg Solti, Leonard Bernstein, Giuseppe Sinopoli, Leopold Stokowski, Eugene Ormandy, Pierre Monteux, William Steinberg and André Previn, as well as leading English conductors from Sir Henry Wood and Sir Adrian Boult to Sir Simon Rattle.
