Question: Sabre Dance is performed in the final act of what ballet created by a leading Soviet composer?

Context paragraphs:
Les Rendezvous: Les Rendezvous is a plotless one-act ballet created in 1933, with choreography by Frederick Ashton to the music of Daniel Auber (the ballet music from his opera "L'enfant prodigue") arranged by Constant Lambert and with designs by William Chappell.  It was the first major ballet created by Ashton for the Vic-Wells company.

Sabre dance (aerodynamics): The Sabre dance is the name given to pitch-up, a particularly dangerous behaviour of swept wings, which became apparent during the development of the USAF F-100 Super Sabre.  When a swept wing starts to stall, the outermost portions tend to stall first.  Since these portions are behind the center of lift, the overall lift force moves forward, pitching the nose of the aircraft upwards.  This leads to a higher angle of attack and causes more of the wing to stall, which exacerbates the problem.  The pilot often loses control, with fatal results at low altitude because there was insufficient time for the pilot to regain control or eject before hitting the ground.  A large number of aircraft were lost to this phenomenon during landing, which left aircraft tumbling onto the runway, often in flames.

Le Conservatoire: Le Conservatoire, or A Marriage by Advertisement ("Konservatoriet eller et Avisfrieri") is a two-act vaudeville ballet created by the Danish choreographer and ballet master August Bournonville in 1849 for the Royal Danish Ballet.  The ballet's setting is a dance studio at the Conservatoire de Paris.  Bournonville studied at the Paris Conservatoire in the 1820s with the renowned dancer Auguste Vestris.  The ballet launched the career of prima ballerina Juliette Price.  A divertissement within the larger work called "The Dancing School" (Pas d'école) permitted Bournonville to display the basics of his style and raise them to the level of enduring art.

Arif Malikov: Arif Malikov (also Melikov; September 13, 1933 in Baku) is an Azerbaijani and Soviet composer.  He graduated from the Baku Conservatory as a music composer in 1958.  He shot to fame in 1961 when his first major composition "Legend of Love" was staged at the Kirov State Academic Theatre of Opera and Ballet in Leningrad (present day St Petersburg) and received nationwide acclaim.  The ballet has been staged in several countries in Europe and is regarded as one of the finest works emerging from the former Soviet Union.  The ballet "Legend of Love", is based upon the legend of "Farhad and Shirin", a story of unrequited love that was immortalized by Turkish poet Nazim Hikmet.  Since then, Malikov has written music for two more ballets including "Yer üzündə iki nəfər (balet)" ("Dvoe" or "Two") (1967) and "Poem of Two Hearts" (1981), five symphonies & eight symphony poems.  He has also written scores for a large number of films and plays and is familiar with practically all genres of music composition.

Carmen Suite (ballet): Carmen Suite is a one-act ballet created in 1967 by Cuban choreographer Alberto Alonso to music by Russian composer Rodion Shchedrin for his wife, prima ballerina assoluta Maya Plisetskaya.  The premiere took place on 20 April 1967 at the Bolshoi Theatre, Moscow.  The music, taken from the opera "Carmen" by Georges Bizet and arranged for strings and percussion, is not a 19th-century pastiche but rather "a creative meeting of the minds," as Shchedrin put it, with Bizet's melodies reclothed in a variety of fresh instrumental colors (including the frequent use of percussion), set to new rhythms and often phrased with a great deal of sly wit.  Initially banned by the Soviet hierarchy as "disrespectful" to the opera for precisely these qualities, the ballet has since become Shchedrin's best-known work and has remained popular in the West for what reviewer James Sanderson calls "an iconoclastic but highly entertaining retelling of Bizet's opera."

Aram Khachaturian: Aram Il'yich Khachaturian ( ; Russian: Ара́м Ильи́ч Хачатуря́н ; Armenian: Արամ Խաչատրյան , "Aram Xačatryan"; ] ; 6 June [O.S. 24 May] 1903 1 May 1978) was a Soviet Armenian composer and conductor.  He is considered one of the leading Soviet composers.

Jazz Calendar: Jazz Calendar is a ballet created in 1968 by Frederick Ashton to the music of Richard Rodney Bennett.  The ballet was first performed on 9 January 1968 by The Royal Ballet at the Royal Opera House, Covent Garden, with designs by Derek Jarman.  The work was performed over 50 times up to 1979 by the Royal Ballet at Covent Garden but is not part of the current repertoire.  It was also produced in October 1990 at the Birmingham Hippodrome by Birmingham Royal Ballet.

Anastasia (ballet): Anastasia is a ballet created by Kenneth MacMillan.  The first version in one act was premiered in 1967 by the Deutsche Oper Ballet.  In 1971 MacMillan expanded the work to three acts for the Royal Ballet; the original one-act version became the final act of the 1971 work.

Sabre Dance: "Sabre Dance" (Armenian: Սուսերով պար, "Suserov par" ; Russian: Танец с саблями, "Tanets s sablyami" ) is a movement in the final act of Aram Khachaturian's ballet "Gayane" (1942), where the dancers display their skill with sabres.  It is Khachaturian's best known and most recognizable work.  Its middle section is based on an Armenian folk song.  According to Tigran Mansurian, it is a synthesis of an Armenian wedding dance tune from Gyumri tied in a saxophone counterpoint "that seems to come straight from America."

Checkmate (ballet): Checkmate is a one act ballet created by the choreographer Ninette de Valois and composer Arthur Bliss.  The idea for the ballet was proposed by Bliss, and subsequently produced by de Valois for the Vic-Wells Ballet.  It was first performed on 15 June 1937 at the Théâtre des Champs-Élysées, Paris.  "Checkmate" is widely regarded as de Valois' signature ballet and a cornerstone of the British ballet repertoire, being performed regularly by the Royal Ballet and Birmingham Royal Ballet.
