Which of the following is NOT an African instrument?

The choice of bagpipes as the instrument that is not African is accurate because bagpipes are historically associated with European cultures, particularly Scotland and Ireland, rather than originating from or being widely used in African musical traditions.

In contrast, conga drums and thumb pianos (often referred to as kalimbas) are both traditional instruments used in various African cultures. Conga drums are used in Afro-Cuban music but have African roots, originating from the Bantu-speaking people of Central Africa. Thumb pianos are traditional to multiple African regions and serve as important instruments in storytelling and cultural expression. Drum ensembles are also integral to African music, where they play a vital role in rituals, celebrations, and various social functions, showcasing the rich diversity of rhythms and styles across the continent.
