"7. Guckulåt efter Joseks Lars 2:27
Mats Rehnberg writes "Even in Nås have several pipers existed. Some of them are known to their name. The foremost is without doubt Gucku Olof Olsson with the soldier name Svedman. The brother was a soldier with the name Sommar and like the father, Gucku Anders, a fiddler. He often played with his sons. In general, it was often pointed out in Nås, that the bagpipe was best heard in combination with the fiddle". (Per säckpipa, Ola fiddle)".
Still doesn't explain what "Gucku" means. A name - a nickname? My wife shook her head when I asked what a "guckulåt" was - "Some tune from Dalarna".
Hey, now finally something makes sense. In Dalarna, where Nås is situated, it is, or was, very common with names of houses and farms. Those names were a part of the persons' names to identify what house or farm someone came from. Gucku is a farm name, as it seems, and Gucku Olof Olsson was simply Olof Olsson from the Gucku farm. So, a Guckulåt must be a tune from the Gucku farm.
