Editing Polytonality (section)

===In traditional music===
Lithuanian traditional singing style [[sutartines]] is based on polytonality. A typical sutartines song is based on a six-bar melody, where the first three bars contain melody based on the notes of the triad of a major key (for example, in G major), and the next three bars is based on another key, always a major second higher or lower (for example, in A major). This six-bar melody is performed as a [[canon (music)|canon]], and repetition starts from the fourth bar. As a result, parts are constantly singing in different tonality (key) simultaneously (in G and in A).{{sfn|Jordania|2006|loc=119–120}}{{sfn|Račiūnaitė-Vyčinienė|2006}} As a traditional style, sutartines disappeared in Lithuanian villages by the first decades of the 20th century, but later became a national musical symbol of Lithuanian music.{{sfn|Anon.|2010}}

Tribes throughout India—including the Kuravan of [[Kerala]], the [[Jaunsari people|Jaunsari]] of [[Uttar Pradesh]], the [[Gondi people|Gond]], the [[Santal people|Santal]], and the [[Munda people|Munda]]—also use bitonality, in [[Call and response (music)|responsorial]] song.{{sfn|Babiracki|1991|loc=76}}
