Professional castanet of the Castañuelas del Sur brand. This model is made using sheets of wood that are bathed in resin. This treatment ensures that the wood does not change its shape in response to changes in temperature, without losing its sound and beauty. This material provides the enchanting sound of natural granadillo, but also the consistency of fibre. The difference between the professional model with a relief and the one without a relief is purely aesthetic, it does not affect the sound at all. The version which has a relief is the traditional castanet, just as we know it. Castañuelas del Sur, the leader in the national and international market as craft manufacturers of castanets for flamenco, constantly pays close attention to the needs of teachers and dance professionals in general, using first-rate materials to satisfy them.
