The music of Iceland includes vibrant folk and pop traditions, as well as an active classical and contemporary music scene. Well-known artists from Iceland include medieval music group Voces Thules, alternative rock band The Sugarcubes, singers Björk and Emiliana Torrini, post-rock band Sigur Rós, indie folk/indie pop band Of Monsters and Men and metal band skálmöld. Iceland's traditional music is related to Nordic music forms. Although Iceland has a very small population, it is home to many famous and praised bands and musicians.
Icelandic music has a very long tradition, with some songs still sung today dating from 14th century. Folk songs are often about love, sailors, masculinity, hard winters, as well as elves, trolls and other mythological creatures, and tend to be quite secular and often humorous. Bjarni Þorsteinsson collected Icelandic folk music between 1906 and 1909, and any of the songs he encountered were accompanied by traditional instruments like the langspil and fiðla, which are among the few musical instruments traditionally played in Iceland. Chain dances, known as víkivaki, have been performed in Iceland since the 11th century at a variety of occasions, such as in churches and during the Christmas season. An example is "Ólafur Liljurós", an Icelandic víkivaki folk song dating to the 14th century, about a man who, while on his way to meet his mother, is seduced, kissed, and stabbed by an elf woman while riding his horse, then eventually dies.
Iceland's isolation meant that, until the 18th century, foreign influences were almost completely absent, which resulted in the maintenance of a particular rhythm, called hákveða, lost in other Nordic countries and considered one of the main characteristics of Icelandic folk music. Hákveða refers to a special emphasis placed on some of the words of a song, often the last word of each sentence in each verse. In the following example, taken from the song "Ólafur Liljurós", hákveða is shown in italics:
