Tchaikovsky is considered as one of the most talented Russian composers of the 19th century. Unlike many other Russian composers of his time, he studied at a conservatory and made the western music theory his own. So, he was not as distrustful of western music as the group of nationalistic composers surrounding Balakirev. Yet, Tchaikovsky sought to express the typical Russian mentality just as much and used many Russian folk songs in his music. He had a good relationship with Balakirev, who helped him with constructive feedback on his first masterpiece, the overture of Romeo and Juliet. At times, Tchaikovsky was emotionally unstable, which has often been attributed to struggles with his homosexuality. His decision to marry proved to be disastrous and plunged him into a deep crisis. Yet, the passionate letters of his fiance, even though they barely knew each other, did inspire him to compose his succesful opera Evgenij Onegin. Tchaikovsky had the wonderful gift of composing the most beautiful, lyric melodies. He had a feeling for creating a certain atmosphere in his music and mastered the art of orchestration. Moreover, he excelled in dance music, which made him the ideal composer for ballet. With his ballets The Swan Lake, The Sleeping Beauty, and The Nutcracker he brought the genre to a higher level. During his life, he was already a celebrity. He often did tours to conduct his music and in the USA he was welcomed as a star. He died unexpectedly, nine days after the premiere of his incredibly gloomy Sixth Symphony, probably of cholera. Some other highlights of his body of works are his First Piano Concerto, his Violin Concerto and the Rococo-variations.

Sergei Vasilievich Rachmaninov was a Russian pianist, composer, and conductor of the late-Romantic period, some of whose works are among the most popular in the classical repertoire.
Born into a musical family, Rachmaninov took up the piano at age four. He graduated from the Moscow Conservatory in 1892 and had composed several piano and orchestral pieces by this time. In 1897, following the critical reaction to his Symphony No. 1, Rachmaninoff entered a four-year depression and composed little until successful therapy allowed him to complete his enthusiastically received Piano Concerto No. 2 in 1901. After the Russian Revolution, Rachmaninov and his family left Russia and resided in the United States, first in New York City. Demanding piano concert tour schedules caused his output as composer to slow tremendously; between 1918 and 1943, he completed just six compositions, including Rhapsody on a Theme of Paganini, Symphony No. 3, and Symphonic Dances. In 1942, Rachmaninov moved to Beverly Hills, California. One month before his death from advanced melanoma, Rachmaninov acquired American citizenship.
Early influences of Tchaikovsky, Rimsky-Korsakov, Balakirev, Mussorgsky, and other Russian composers gave way to a personal style notable for its song-like melodicism, expressiveness and his use of rich orchestral colors.[3] The piano is featured prominently in Rachmaninov's compositional output, and through his own skills as a performer he explored the expressive possibilities of the instrument.
