are the "Griegslåttarna". In the year 1889 the fiddler, Knut Johannesen Dahle (1834 - 1921), from Tinn i Telemark, Norge, wrote to the composer, Edvard Grieg, to ask him to write down norwegian folktunes. However, Edvard Grieg, let Knut Dahle play for Johan Halvorsen who then sent the sheet music to Edvard Grieg. The result was 17 tunes, "slåttar". Edvard Grieg then used them as an inspiration to the klassic compositions he made.
The performans of the consert First I play a "slått", then the piano player plays the Grieg composition based on the played "slått". During a consert, seven "slåttar" cover a one hour consert.
