Sylvia, originally Sylvia, ou La nymphe de Diane, is a full-length ballet in two or three acts, first choreographed by Louis Mérante to music by Léo Delibes in 1876. Sylvia is a typical classical ballet in many respects, yet it has many interesting features that make it unique. Sylvia is notable for its mythological Arcadian setting, creative choreographies, expansive sets and, above all, its remarkable score.

The ballet's origins are in Tasso's 1573 play Aminta, which provides the basic plot of Delibes' work. Jules Barbier and Baron de Reinach adapted this for the Paris Opera. The piano arrangement was composed in 1876 and the orchestral suite was done in 1880.

When Sylvia premiered on Wednesday, June 14, 1876, at the Palais Garnier, it went largely unnoticed. In fact, the first seven productions of Sylvia were not commercially successful. It was the 1952 revival, choreographed by Sir Frederick Ashton, that popularized the ballet. Ashton's success set the stage for the 1997, 2004, 2005 and 2009 productions, all of which were based on his 1952 choreography.

History
Preparations
In 1875, the Paris Opera chose Barbier and Reinach's libretto for Sylvia. Mérante was also chosen to choreograph Sylvia based primarily on his extensive experience in the field and position as the premier maître de ballet at Paris Opera. All other reasonable choreographers were at the time unavailable.

Rehearsals for Sylvia begin on August 15, 1875, with only the first third of the music intact. Throughout the rehearsal period the score was under constant revision by Delibes, often with the "aid" of Mérante and Rita Sangalli who would each dance a lead rôle. This development of the score was a grueling process of many revisions and restarts. Mérante was especially demanding of Delibes and would regularly request changes to the score to accommodate his choreography, yet Léo Delibes made the changes requested of him in a timely fashion.

1876: Paris Opera Ballet; Mérante
Sylvia, ou la nymphe de Diane, as it was originally titled, was the first ballet to be shown at the newly constructed Opera Garnier and it did so with extravagance. This approach proved at times excessive. The lavish scenery of Jules Chéret was poorly lit, detracting from the quality of the production. The costumes designed by Lacoste were well appreciated, however. In the end it was Delibes' score that saved the production. Without such highly esteemed music, the ballet would have soon drifted into obscurity.

At the age of 27, Rita Sangalli was the principal ballerina at the Opéra, and thus the obvious choice to star as Sylvia. Sangalli was described as having a "superb physique",[citation needed] but not spectacular dancing skills. Nonetheless, she was the only ballerina taught the rôle, and on one occasion the ballet had to be temporarily closed when she injured herself.

Music
Sylvia, and Coppélia before it, are often touted[by whom?] as two of the first modern ballets for their novel scores. Tchaikovsky himself remarked to fellow composer Sergei Taneyev upon the ingenuity of Sylvia, calling it "... the first ballet, where the music constitutes not only the main, but the only interest. What charm, what elegance, what richness of melody, rhythm, harmony."While this statement may be a little hyperbolic, it says something very important about the uniqueness of the ballet. Sylvia's score is varied and rich, and it stands out, drawing the focus from the sets, the dancers, the costumes. Instead of receding into the background, setting only the mood, Delibes' score sets the action. The music of Sylvia was also notable for its new, more developed use of leitmotifs. Such a stylistic choice is characteristic of Delibes, who was a great admirer of Wagner. Indeed, echoes of Wagner's influence are quite obvious in the music such as its "symphonic" nature, as described by Ivor Forbes Guest in the 1954 edition of The Ballet Annual.

Another interesting choice of Delibes was his pronounced use of brass and wind instruments, especially in the characteristically powerful prelude. Delibes was also one of the first composers to write for the alto saxophone, an instrument used extensively in the heavier wind sections such as the barcarolle in Act III.

The prelude to the first act and the pizzicati in the third are the significantly more famous sections of this already notable score. The latter, the more famous, is a well-known example of pizzicato style. This section is, according to The New Grove Dictionary of Music and Musicians, "traditionally played in a halting, hesitant style that appears to have been no part of Delibes's conception."

Tchaikovsky's Swan Lake was written just before Sylvia was released and is generally considered[by whom?] one of the best ballets of the era. However, Tchaikovsky himself preferred Sylvia to his own work, calling his own masterpiece "poor stuff in comparison". Tchaikovsky said to Sergei Taneyev, "I was ashamed. If I had known this music early then, of course, I would not have written Swan Lake".

Choreography

Choreographically, Sylvia was also ahead of its time. Merante's 1876 choreography (and all subsequent) was considered quite rebellious for casting ballerinas as masculine huntresses, unheard of at the time. Despite such innovations, the original choreography for Sylvia was still very much of late Romantic-era ballet.[citation needed]

Ashton's Sylvia is much more contemporary, and while retaining a classic feel, it has been modernized. In the 1952 choreography, Sylvia incorporated new and interesting techniques such as the blending of mime and dance and more intricate footwork, as are typical of Ashton's works. As writer Arnold Haskell said, "he accepts the challenge in Sylvia of coping with period music without descending to pastiche; and never once does the movement he provides strike us as modern or as 'old world'". Gillian Murphy, the lead rôle in the 2005 ABT production, noted this choreography was very challenging. Ashton designed the ballet specifically around Margot Fonteyn's talent and skill. Thus, any who play the part must be able to do everything she could, and at the time "the range of her dancing [was] unequalled"(Barnes).

It is notable that this choreography features a few difficult pas de deux, including a spectacular one in the third act, which constitutes the climax of the ballet.
