The festival, which runs from July 3rd-6th, is billed as the biggest event ever to be staged in the small community of Davos-Klosters in the canton of Graubünden.
Some 10,000 yodellers, alphorn players, flag wavers and flag throwers will perform during this annual meet of the Federal Yodelling Association.
The event kicks off this afternoon with a panel discussion about the alphorn, before performances begin tomorrow.
Participants include Marcus Cavetti, a well-known player of the alphorn and büchel, a traditional bugle-like instrument from central Switzerland.
To cope with the crowds, the Rhaetian Railway, which serves the area, is recycling previously scrapped goods wagons to create extra passenger carriages, reports news agency ATS.

The weather may provide more of an obstacle, however. Though sunshine is expected for Thursday and Friday, rain is forecast for Davos, Europe’s highest village, over the weekend.
