Catá
The catá or guagua is a Cuban percussion instrument which originated in the eastern region of the island. It is classified as a directly struck idiophone, traditionally made out of a hollowed tree trunk, which the player hits with wooden sticks or mallets. The resulting sound is dry and penetrating, similar to that of the claves, although with a different pitch.[1] Of Congolese origin, it is an essential instrument in tumba francesa, yuka and some rumba ensembles.
