Grig (1843.6.15~1907.9.4), a Norwegian composer, pianist and founder of the Norwegian national music school, was born in Bergen. His father is originally from Scotland and his mother is from Norway. He learned piano from his mother when he was young. When he was 15 years old, he was recommended by the famous violinist Boer to study in Germany and entered the Leipzig Conservatoire to study composition and piano. After graduating from the college in 1862, he returned to China. At the age of 21, he met the Norwegian folk music composer Nodrak (1842~1866, author of the Norwegian national anthem). Inspired by him, he devoted himself to the research of folk music and used it in his creation. At the same time, he toured all over Europe. . In 1868, he composed the youthful and energetic "Piano Concerto in A minor". In 1869, he met Liszt in Rome. He also co-founded the "Norwegian Music Association" in Oslo (the capital). In 1874 (31 years old), he received a lifetime annuity from the Norwegian government and moved to Bergen. In his rural life, he enjoyed the freshness of nature and the simple life of the villagers, and devoted himself to composing music. He contracted an illness and died in hospital in 1907 before going to England. He composed the drama soundtrack "Peer Gynt" (1874~1875), ten volumes of "Piano Lyrics" (***66 songs), orchestral music "Norwegian Dances" (***4 songs, 1881), "Norwegian Dances" (***4 songs, 1881), "Hallburg Suite" (1884~1885, composed to commemorate the 200th anniversary of the poet Hallburg's birth), as well as a large number of art songs, etc.

The creations of Tchaikovsky, Sibelius, Debussy and others have all been influenced by it. Grieg formed a unique style of art music on the fertile soil of folk songs. In terms of harmony, he not only has a strong romantic style, but also presents an impressionistic harmonic vocabulary, which is one of his most creative contributions. His title piano sketch is unique in that it extensively adopts the rhythm of folk dance music and uses folk songs as its melody material.
