Sergei Rachmaninoff
1873 | April 1 – 1943 | March 28
Duration approximately 35 minutes

Rachmaninoff is well known for his piano compositions. Born as Russian composers and influenced by Tchaikovsky and Rimsky-Korasakov, all of his compositions required maturity in technique and character; this is especially true in all of his three piano concertos. Tonight’s piano concerto no. 2 has a deep root of Russian heritage in Rachmaninoff’s ink writings. Though it is dark yet this concerto is full of rich harmonies and emotional attachment throughout the movements – which made it one of the most beloved and most performed piano concertos of the Romantic period. Its premiere was performed by the composer itself and with his brother, Alexander Siloti conducting.

The first movement is dark and full of power, right from the beginning, the music drawn us only to the soloist with series of chords as introduction. The second movement starts slow and full of beautiful melodies, when the piano took over with triplets, the conjunction between the piano and orchestra is remarkable. The last movement is very vivacious and full of energy. The movement ends with power and glory.

Johannes Brahms
1833 | May 7 – 1897 | April 3
Duration approximately 6 minutes (3 minutes each)

When Brahms was 17, he met a famous Hungarian violinist, Eduard Reményi. Three years later, Brahms accompanied him on a concert tour. It was then, he encountered the spirited and virtuosic Hungarian “Gypsy” themes which inspired him to compose the notable Hungarian Dances. However, Brahms mistakenly thought that these tunes were authentically Hungarian folk music while it was the work of another Hungarian composer, played by the gypsy band in a café or restaurant. Nevertheless, Brahms was fascinated by this fiery music that he produced 21 Hungarian Dances for four-hands piano. Later, he and his few other friends, including Antonin Dvorak, arranged it for the orchestra. Hungarian Dance No. 5 is one of the better-known Hungarian Dances. It was based on Csárdás “Bártfai emlék” (Reminiscences of Bartfai Czárdás), composed by Hungarian composer Béla Kéler. It has a strong csárdás characteristic, where the melody started slow, then it builds up, getting faster and more dramatic. The melody of Hungarian Dance No. 6 was adapted from Rózsa Bokor song (Rosebush), by Adolph Nittinger. Similar to Hungarian Dance No. 5, it is heavily influenced by csárdás style. It contains great contrast between the passages, the slow-lyrical and the fast-bouncy. Overall, it was dramatic and amusing for everyone to enjoy.

Pyotr Ilyich Tchaikovsky
1840 | May 7 – 1893 | November 6
Duration approximately 5 minutes

As Johann Strauss II introduces the art of waltz Music to the world, many composers of the Romantic Era started to explore this genre, including Tchaikovsky himself. Unlike the traditional Viennese waltzes that are fast in tempo, containing melodious tunes with simple triple time harmonic progression and strong downbeat designed for the ballroom social dance, Tchaikovsky’s waltzes contain countermelodies, syncopation, moving melodic lines in the bass to create a theatrical but elegant effect to accompany the dances and actions in his ballets and operas.

One of his signature waltz featured tonight is the Waltz from Tchaikovsky’s ballet in 3 acts, Sleeping Beauty Op. 66. Based on the fairytale “La belle au bois dormant” by Charles Perrault, Sleeping Beauty tells a story of an enchanted princess that was cursed by an evil witch that she will fall into a deep sleep once she gets poked by a needle or thorn. While unfortunately the princess did succumb to the curse years later, a young prince came to the rescue to break the spell. Sleeping Beauty was composed in the months between December 1888 and September 1889, commissioned by the Director of the Imperial Theaters at St. Petersburg, and had its premiere in St. Petersburg’s famous Mariinsky Theatre on January 15, 1890. The well-known waltz sets the scene for a festive gathering announcing the birth of the princess in the king’s palace in Act I.

Gioacchino Rossini
1792 | February 29 – 1868 | November 13
Duration approximately 2 minutes

La scala di seta (The Silken Ladder) was composed when Rossini was 20 years old. It is a short opera about the protagonist, Dorvil, who climbed to Giulia’s room using a silk ladder every night. Giulia is Dorvil’s secretly married wife. One morning, Dorvil’s attempt to escape was hindered by the appearance of Giulia’s cousin and servant. Giulia’s guardian, Dormont, insisted that she must marry Blansac, without knowing that Giulia was already married to Blansac’s friend, Dorvil. Giulia tried to divert Blansac’s amorous love toward her cousin, while Dorvil tried to convince Blansac that Giulia was not looking for a husband at the moment. The overture is light and lively, with some lyrical moments. It begins with a descending scale by the strings, then followed by the lyrical oboe. It paints of the morning operatic scenery. Then, the strings entered with a hurrying motif, followed by the woodwinds, expressing some comical element. Romantic and humorous, the entire overture represents the opera itself.

Léo Delibes
1836 | February 21 – 1891 | January 16
Duration approximately 2 minutes

Delibes was an influential French composer, best known for his opera and ballet music compositions. His works, such as Coppélia, played an important role in the development of modern ballet. His symphonic work for ballet inspired many composers afterwards one among them includes Tchaikovsky. His music is graceful and elegant, with strong impressionistic style. He mastered the ability to utilize orchestral musical colors in order to create a particular ambience or mood. Coppélia is a ballet based on E.T.A Hoffmann’s story, “The Sandman”, a dark psychological story. However, Delibes managed to wrap it up in a milder, delicate way. Coppélia is about a man called Franz, who was infatuated with a life-like mechanical doll, Coppélia. However, Franz’s real-life fiancé, Swanilda was unhappy with the situation and tried to intervene. The Waltz originates from the First Act as Swanilda attempt to attract the attention of Coppélia, which was sitting still and reading by the window of Dr. Coppélius’ house, its inventor. The music is graceful and light. The beautiful main melody was played by the strings. It ends swiftly with a series of chromatic and arpeggios passage.

Émile Waldteufel
1837 | December 9 – 1915 | February 12
Duration approximately 8 minutes

Written in 1882, the Skaters' Waltz paints images of the events of a very cold day in 1879, the year Europe had one of the coldest winter on record. Sleighs were used through the streets of Paris, and Parisians skated on the frozen French Seine River.

There is a slow introduction with a motif played by the horn, followed by rapid flute trills and violin glissando, suggesting the exciting idea to skate on the river. The entrance towards the main theme sounds tentative, portraying people timidly trying the ice. As the opening section of the Waltz with the main melody begins in the dance tempo, it symbolizes that people begin to feel secure to enjoy skating since the ice is firm. The second section with shorter and lighter phrases paints the falling snow. The longer phrases paint the skaters enjoying the smoothness of the ice. The staccato phrases with the brass paints the skaters doing some turns and jumps. During the transition, it sounds like one of the skaters fell down, but resume skating as the opening section returns. At the end, there is a hint of sleigh bells before the timpani bring closes the Waltz.

Gioacchino Rossini
1792 | February 29 – 1868 | November 13
Duration approximately 10 minutes

La Gazza Ladra (The Thieving Magpie) was composed in 1817 when the young Rossini was at his peak career. It is a semi-serious opera (otherwise known as semiseria opera), a combination of serious opera and comical opera. Based on a true event in France, this opera recites a story of a young female servant being accused of stealing a silver spoon and was eventually sentenced to death. Right before she was executed, it was revealed that a magpie (type of bird which fond of shiny things) is the real silverware thief. Just like most of Rossini’s opera, it has a happy ending. The overture is splendor yet amusing. It begins with a snare drum roll, followed by the main melody in a marching military style. The music creates a majestic entrance. A series of snare drum rolls ends the first section with grandeur. The following minor section depicts the lamenting young servant in the jail. The ending section is in typical Rossini style, where the main theme played softly on repeat, gradually getting larger and bolder. Then, a rapid brilliant passage finishes the overture splendidly.
