There are five groups of Sub-Saharan African musical instruments: membranophones, chordophones, aerophones, idiophones, and percussion. Membranophones are the drums, including kettles, clay pots, and barrels. Chordophones are stringed instruments like harps and fiddles. Aerophones are another name for wind instruments. These can include flutes and trumpets, similar to the instruments you hear in American music. Idiophones are rattles and shakers, while percussion can be sounds like foot-stomping and hand-clapping. Many of the wooden instruments have shapes or pictures carved out into them to represent ancestry. Some are decorated with feathers or beads.
