A joik or yoik (anglicised, where the latter spelling in English conforms with the pronunciation; also named luohti, vuolle, vuelie, or juoiggus in the Sámi languages) is a traditional form of song in Sámi music performed by the Sámi people of Sapmi in Northern Europe. A performer of joik is called a joikaaja (in Finnish), a joiker (in Norwegian, and anglicised) or jojkare (in Swedish). Originally, joik referred to only one of several Sami singing styles, but in English the word is often used to refer to all types of traditional Sami singing. As an art form, each joik is meant to reflect or evoke a person, animal, or place..
The sound of joik is comparable to the traditional chanting of some Native American cultures. Joik shares some features with the shamanistic cultures of Siberia, which mimic the sounds of nature.
