Waulking songs (Scottish Gaelic: Òrain Luaidh) are Scottish folk songs, traditionally sung in the Gaelic language by women while fulling (waulking) cloth. This practice involved a group of women, who traditionally prepared cloth, rhythmically beating newly woven tweed or tartan cloth against a table or similar surface to lightly felt it and shrink it to better repel water. Simple, beat-driven songs were used to accompany the work.
A waulking session often begins with slow-paced songs, with the tempo increasing as the cloth becomes softer. As the singers work the cloth, they gradually shift it to the left so as to work it thoroughly. A tradition holds that moving the cloth anticlockwise is unlucky.
