Pyotr Ilyich Tchaikovsky in the context of "Gustav Mahler"

Swan Lake (Russian: Лебеди́ное о́зеро, romanized: Lebedínoje ózero, Russian pronunciation: [lʲɪbʲɪˈdʲinəjə ˈozʲɪrə]), Opus 20, is a ballet composed by Pyotr Ilyich Tchaikovsky between 1875 and 1876. The original production premiered at the Bolshoi Theatre in Moscow on 4 March 1877 (20 February Old Style), with choreography by Julius Reisinger. The ballet, initially conceived in two acts, is based on Russian and German folk tales and tells the story of Princess Odette, who is transformed into a swan by the sorcerer Von Rothbart.

The initial reception was lukewarm, with criticism directed at various elements of the production. Despite this, Swan Lake has become one of the most frequently performed ballets worldwide.

Sleeping Beauty is a 1959 American animated musical fantasy film produced by Walt Disney Productions and released by Buena Vista Film Distribution. Based on Charles Perrault's 1697 fairy tale, the film follows Princess Aurora, who was cursed by the evil fairy Maleficent to die from pricking her finger on the spindle of a spinning wheel on her 16th birthday. She is saved by three good fairies, who alter Aurora's curse so that she falls into a deep sleep and will be awakened by true love's kiss. The production was supervised by Clyde Geronimi, and was directed by Wolfgang Reitherman, Eric Larson, and Les Clark. It features the voices of Mary Costa, Bill Shirley, Eleanor Audley, Verna Felton, Barbara Luddy, Barbara Jo Allen, Taylor Holmes, and Bill Thompson.

Sleeping Beauty began development in 1950. The film took nearly a decade and $6 million (equivalent to $64,719,178 in 2024) to produce, and was Disney's most expensive animated feature at the time. Its tapestry-like art style was devised by Eyvind Earle, who was inspired by pre-Renaissance European art; its score and songs, composed by George Bruns, were based on Pyotr Tchaikovsky's 1889 ballet. Sleeping Beauty was the first animated film to use the Super Technirama 70 widescreen process and was the second full-length animated feature filmed in anamorphic widescreen, following Lady and the Tramp (1955).

A music school is an educational institution specialized in the study, training, and research of music. Such an institution can also be known as a school of music, music academy, music faculty, college of music, music department (of a larger institution), conservatory, conservatorium or conservatoire (/kənˈsɜːrvətwɑːr/ kən-SER-və-twar, French: [kɔ̃sɛʁvatwaʁ]). Instruction consists of training in the performance of musical instruments, singing, musical composition, conducting, musicianship, as well as academic and research fields such as musicology, music history and music theory.

Music instruction can be provided within the compulsory general education system, or within specialized children's music schools such as the Purcell School. Elementary-school children can access music instruction also in after-school institutions such as music academies or music schools. In Venezuela El Sistema of youth orchestras provides free after-school instrumental instruction through music schools called núcleos.

Ernst Theodor Amadeus Hoffmann (born Ernst Theodor Wilhelm Hoffmann; 24 January 1776 – 25 June 1822) was a German Romantic author of fantasy and gothic horror, a jurist, composer, music critic and artist. He is the author of the novella The Nutcracker and the Mouse King, on which Pyotr Ilyich Tchaikovsky's ballet The Nutcracker is based. In addition, his stories form the basis of Jacques Offenbach's opera The Tales of Hoffmann, in which Hoffmann appears (heavily fictionalized) as the hero. The ballet Coppélia is based on two other stories that Hoffmann wrote, while Schumann's Kreisleriana is based on Hoffmann's character Johannes Kreisler.

Hoffmann's stories highly influenced 19th-century literature, and he is one of the major authors of the Romantic movement.

Alexander Konstantinovich Glazunov (10 August [O.S. 29 July] 1865 – 21 March 1936) was a Russian composer, music teacher, and conductor of the late Russian Romantic period. He was director of the Saint Petersburg Conservatory between 1905 and 1928 and was instrumental in the reorganization of the institute into the Petrograd Conservatory, then the Leningrad Conservatory, following the Bolshevik Revolution. He continued as head of the Conservatory until 1930, though he had left the Soviet Union in 1928 and did not return. The best-known student under his tenure during the early Soviet years was Dmitri Shostakovich.

Glazunov successfully reconciled nationalism and cosmopolitanism in Russian music. While he was the direct successor to Balakirev's nationalism, he tended more towards Borodin's epic grandeur while absorbing a number of other influences. These included Rimsky-Korsakov's orchestral virtuosity, Tchaikovsky's lyricism and Taneyev's contrapuntal skill. Younger composers such as Prokofiev and Shostakovich eventually considered his music old-fashioned, while also admitting he remained a composer with an imposing reputation, and a stabilizing influence in a time of transition and turmoil.

The celesta (/sɪˈlɛstə/) or celeste (/sɪˈlɛst/), also called a bell-piano, is a struck idiophone operated by a keyboard. It looks similar to an upright piano (four- or five-octave), albeit with smaller keys and a much smaller cabinet, or a large wooden music box (three-octave). The keys connect to hammers that strike a graduated set of metal (usually steel) plates or bars suspended over wooden resonators. Four- or five-octave models usually have a damper pedal that sustains or damps the sound. The three-octave instruments do not have a pedal because of their small "table-top" design. One of the best-known works that uses the celesta is Pyotr Ilyich Tchaikovsky's "Dance of the Sugar Plum Fairy" from The Nutcracker.

The sound of the celesta is similar to that of the glockenspiel, but with a much softer and more subtle timbre. This quality gave the instrument its name, celeste, meaning "heavenly" in French. The celesta is often used to enhance a melody line played by another instrument or section. Its musical parts are often the duplicate of a theme played on flute, harp or piano; sometimes even a real solo part. It is also used in chamber music, but there are very few concertos written for it. The delicate, bell-like sound is not loud enough to be used in full ensemble sections.

Pyotr Ilyich Tchaikovsky was a Russian composer especially known for three very popular ballets: Swan Lake, The Sleeping Beauty and The Nutcracker. He also composed operas, symphonies, choral works, concertos, and various other classical works. His work became dominant in 19th century Russia, and he became known both in and outside Russia as its greatest musical talent.

The Nutcracker (Russian: Щелкунчик, romanized: Shchelkunchik, pronounced [ɕːɪɫˈkunʲt͡ɕɪk] ), Op. 71, is an 1892 two-act classical ballet (conceived as a ballet-féerie; Russian: балет-феерия, romanized: balet-feyeriya) by Pyotr Ilyich Tchaikovsky, set on Christmas Eve at the foot of a Christmas tree in a child's imagination featuring a Nutcracker doll. The plot is an adaptation of Alexandre Dumas's 1844 short story The Nutcracker, itself a retelling of E. T. A. Hoffmann's 1816 short story The Nutcracker and the Mouse King. The ballet's first choreographer was Marius Petipa, with whom Tchaikovsky had worked three years earlier on The Sleeping Beauty, assisted by Lev Ivanov. Although the complete and staged The Nutcracker ballet was not initially as successful as the 20-minute Nutcracker Suite that Tchaikovsky had premiered nine months earlier, it became popular in later years.

Since the late 1960s, The Nutcracker has been danced by many ballet companies, especially in North America. Major American ballet companies generate around 40% of their annual ticket revenues from performances of the ballet. Its score has been used in several film adaptations of Hoffmann's story.
