Editing Kalevala (section)

====Form and structure====
The poetry was often sung to music built on a [[pentachord]], sometimes assisted by a [[kantele]] player. The rhythm could vary but the music was arranged in either two or four lines in [[Quintuple meter|{{music|time|5|4}}]] metre.{{Citation needed|reason = Five beat music, four beat poem?|date=August 2010}} The poems were often performed by a duo, each person singing alternative verses or groups of verses. This method of performance is called an [[antiphon]]ic performance, it is a kind of "singing match".
