These are the castanets that my husband bought me as a treat because I kept going on about how much I would like to learn how to play them properly! Although they look like quite a simple percussion instrument, the variety of sounds and rhythms that can be produced is amazing. To help me on the right track I watch a lot of YouTube videos!! There are lots in English to start you off, but the most helpful one I found was – Castanet Playing . It doesn’t matter too much if you are not a confident Spanish speaker, as you can watch closely at what the lady is doing and play along with her!
I think I probably annoy all the sheep in the evening by practising while I am making supper! They had better get used to it, because these are here to stay!
