Finnish folk music can be divided into Nordic dance music and the older tradition of poem singing, poems from which the national epic, the Kalevala, was created. Much of Finland's classical music is influenced by traditional Finnish and Karelian melodies and lyrics, as comprised in the Kalevala. In the historical region of Finnish Karelia, as well as other parts of Eastern Finland, the old poem singing traditions were preserved better than in the western parts of the country, thus Karelian culture is perceived as less influenced by Germanic influence than the Nordic folk dance music that largely replaced the kalevaic tradition. Finnish folk music has undergone a roots revival and has become a part of popular music. The people of northern Finland, Sweden, and Norway, the Sami, are known primarily for highly spiritual songs called joik.
