"Ievan polkka" (Finnish for "Ieva's Polka") is a Finnish song with lyrics printed in 1928[1] and written by Eino Kettunen to a traditional Finnish polka tune. The song is sung in an Eastern Savonian dialect spoken in North Karelia. It is sung from the point of view of a young man, about a woman called Ieva (dialectal for the name Eva or Eeva in standard Finnish) who sneaks out and dances the polka with him all night. The song is often mistaken for a traditional folk song, but the lyrics by Eino Kettunen are still under copyright. Later, a scat singing version of the song by the band Loituma was incorporated into the viral animation Loituma Girl. In 2007, the song was brought into worldwide popular culture through a cover sung by Hatsune Miku, with Otomania arranging the music and providing Miku's voice manipulation.
