This holds true for the practices of the noaidi among Sami groups. Although the Sami people live outside of Siberia, many of their shamanistic beliefs and practice shared important features with those of some Siberian cultures. The joiks of the Sami were sung on shamanistic rites. Recently, joiks are sung in two different styles: one of these is sung only by young people; the traditional one may be the other, the "mumbling" style, which resembles magic spells. Several surprising characteristics of joiks can be explained by comparing the music ideals, as observed in joiks and contrasted to music ideals of other cultures. Some joiks intend to mimic natural sounds. This can be contrasted to bel canto, which intends to exploit human speech organs on the highest level to achieve an almost "superhuman" sound.
