This metal castanet-like instrument is of Berber origin and is still used today in Morocco. They are used in pairs – one in each hand – and are very heavy. Each one is at least one foot long. While watching them used by the musicians accompanying the dancers, I only saw men playing them. Think that is due to the fact that they are difficult to play due to their heaviness. They do make a loud noise. I bought them in Agadir – a city along the coast of Morocco – from the man who was playing them after the folk-dance performance ended. The musician and I made a deal through our guide. They certainly added weight to my suitcase. However, it did help that we had our own car as Ann Power and I had driven to Morocco from Madrid. Spent our Christmas holiday in that country in 1967.
