The “krakebs” are a large handmade iron castanet-like idiophone primarily used as the rhythmic aspect of Gnawa music. They are handheld cymbal-type instruments consisting of four cymbals (two held in each hand) attached by a string and are played much like castanets. Oral history says they represent the sound of horse’s hooves hitting the round as the people were carried away in grain sacks, and the rattling of shackles that used to hold the people captive. Each of the cymbals has a prominent raised middle section and incised scalloping around the edge which continues around the entire edge of each set. A Krareb performer was performing at Chefchaouen at night.
