Where did the ago go bells come from?

The "ago go" bells, also known as agogô bells, originated from West African musical traditions, particularly among the Yoruba people. They were brought to Brazil through the transatlantic slave trade and became a significant element in Afro-Brazilian music, especially in samba and other cultural expressions. The bells are typically made of metal and produce distinct, resonant sounds, often used to keep rhythm in various musical styles.
