What poetic metre was commonly used in traditional Finnish folk poetry?

Traditional Finnish folk poetry is characterized by a specific poetic metre known as the Kalevala metre. This form consists of an unrhymed, trochaic four-stress line.12

This metre was particularly well-suited to the Finnish language and facilitated the memorization of long passages during the oral transmission of poems. In addition to its distinct rhythmic structure, the style of this poetry is defined by the use of alliteration, parallelism, and repetition. These elements are central to the Kalevala, the Finnish national epic compiled by Elias Lönnrot, which preserves the rich tradition of these ancient ballads, lyrical songs, and incantations.21
