Traditionally, joiks have short lyrics or no lyrics at all. 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.
