This mohoceño is one of a number of professional quality Bolivian instruments in the Horniman collection made by the Bolivian-based instrument maker Arian Villanueva. Mr Villanueva provided the following information about the instrument: it is found all over Boliva and is representative of Aymara culture. In Walata, Mr Vallanueva's home town, mohoceños are played in large groups with the caja drum at weddings, birthdays and carnivals. Sometimes a trumpet, an instrument introduced from Europe, will also play with the group.
