Professional castanet of the Castañuelas del Sur brand. This model has a double soundbox and relief, and is made using sheets or strips of paper that are impregnated in resins.
The main characteristics of this castanet, which distinguish it from those with a traditional sound-box, are that it weighs less and its sound is more gruff, or flamenco.
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.
