"Cuatro" is the Spanish word for the number four. It is used in various contexts, such as counting, mathematics, and everyday conversation. In many cultures, the number four can symbolize stability and balance, often represented by the four cardinal directions: north, south, east, and west. In music, "cuatro" also refers to a stringed instrument popular in Latin American countries, particularly in Puerto Rico. The instrument typically has four strings and is played similarly to a guitar. It is an essential part of traditional folk music and contributes to the rich cultural heritage of the region.
