This can be seen in his use of Norwegian melodies and rhythms, as well as his incorporation of traditional folk instruments such as the Hardanger fiddle.
Grieg also wrote a number of pieces that evoke the natural beauty and landscapes of Norway, such as his "Peer Gynt" suites and his "Lyric Pieces."
Through his music, Grieg helped to establish a Norwegian national identity and played an important role in promoting Norwegian culture and music around the world.
