Castanets are fascinating in both their sound and role. They essentially define Spanish dance music, such as flamenco, but their rhythmic character also blends well with classical instruments. It’s a unique and beguiling combination, especially in the hands of harpist Xavier de Maistre and Lucero Tena, a virtuoso of flamenco and the castanets. They’ve created a program inspired by Spanish music and composers sure to take the audience on a musical tour of the Mediterranean country. The pieces, such as “Suite española” by Albéniz, conjure the locales and regions of his homeland.
