Kanteletar is a collection of Finnish folk poetry compiled by Elias Lönnrot. It is considered to be a sister collection to the Finnish national epic Kalevala. The poems of Kanteletar are based on the trochaic tetrameter, generally referred to as "Kalevala metre". The name consists of the base word kantele (a Finnish zither-like instrument) and the feminising morpheme -tar and can be roughly interpreted as "maiden of the kantele" or "zither-daughter", a kind of muse.
