Traditionally, joiks have short lyrics or no lyrics at all.[citation needed] However, there are other forms of joik (in the expanded sense of the word) that have a more epic type of lyrics. Joik is traditionally chanted a cappella, but in modern times may be accompanied by a drum (though not a Sami drum, which is used for ceremonial purposes only) or other musical instruments. The tonality of joik is mostly pentatonic, but joikers are at liberty to use any tones they please.
In northern Sami areas, most joiks are personal, that is, tied to a specific person. A joik is often made for a person at the time he or she is born. British actress Joanna Lumley experienced several joiks during her travel program Joanna Lumley in the Land of the Northern Lights, joining a northern Sami elder. Lumley learned that there appeared not to be a joik of the Northern Lights, and that the Sami do not talk much about them.
