Polisävelaskelma

Polisävelaskelma refers to a musical concept in Finnish folk music, specifically a melodic pattern or phrase that is characteristic of certain regional styles or even individual musicians. It's not a formal scale in the Western classical sense but rather a recognizable melodic contour or sequence of notes that lends a distinct flavor to a tune. These patterns often emerge organically from the improvisational traditions within folk music.

The term literally translates to "police scale" or "police stepwise motion," but this has no connection to law enforcement. The "polis" element is thought to derive from an older Finnish word or dialectal term, or perhaps it's a playful or descriptive name that stuck. The "askelma" part refers to the stepwise movement, highlighting the melodic shape.

Polisävelaskelma can be identified by its specific intervals and rhythmic phrasing. It might involve characteristic leaps, repeated notes, or a particular way of descending or ascending a melodic line. These elements contribute to the unique identity of a folk tune, making it recognizable as belonging to a certain tradition or performed by a particular artist. While not always consciously taught, these melodic ideas are passed down through oral tradition and learned by ear by musicians. Understanding polisävelaskelma is key to appreciating the nuances and regional variations within Finnish folk music.
