What is "erikundi"

The erikundi is a percussive instrument that is shaken much like a maraca. Unlike the maraca, however, it is made from other materials, causing a different sound to be heard. The Erikundi is also related to the Abakua cult, an Afro-Cuban Secret Society, and the playing of it may indicate an individual’s solidarity to this society. Additionally the diversity of this instrument and its use is illustrated by its use in popular music ensembles such as Vieja Trova.
