Description on old index card: "Small reddish-brown ivory horn, ending in a figurine that rests the chin on the hands" In addition to the Bangwa, this type of transverse trumpet was also used by groups from the Cameroon forest region, such as the Bakundu, Bago, Balong and others. Such musical instruments were used by the Musongo secret society (E. Haase 2013). Richard Tsogang Fossi said in 2020 that they were blown at the arrival of a chief or to warn of danger. The spelling of the cultural attribution varies in the sources; on the old index cards in the museum, the term "Bangua" is predominantly used.
