Edvard Hagerup Grieg was a Norwegian composer and pianist. He is widely considered one of the leading Romantic era composers, and his music is part of the standard classical repertoire worldwide. His use and development of Norwegian folk music in his own compositions put the music of Norway in the international spectrum, as well as helping to develop a national identity, much as Jean Sibelius and Antonín Dvořák did in Finland and Bohemia, respectively.
Grieg is regarded as simultaneously nationalistic and cosmopolitan in his orientation, for although born in Bergen and buried there, he travelled widely throughout Europe, and considered his music to express both the beauty of Norwegian rural life and the culture of Europe as a whole. He is the most celebrated person from the city of Bergen, with numerous statues depicting his image, and many cultural entities named after him.

Jean Sibelius (1865-1957) was the composer who gave Finland its own sound, right when this nation was struggling to detach itself from Russia. Sibelius wrote several impressive symphonic poems - among which Finlandia, Lemminkäinen-suite, Oceaniden, Tapiola - for he took inspiration from the Kalevala, the Finnish national epic. He was just as original as a symphonist: his Seven Symphonies are just as much answers to the question how the genre should develop after Tchaikovsky's death.

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.
