A maraca is a percussion instrument commonly used in various music genres, especially in Latin American and Caribbean music. It typically consists of a hollow body filled with beads or seeds, which creates sound when shaken. Maracas are often made from materials like wood, plastic, or gourd, and they come in different sizes and designs. Musicians play maracas by holding one in each hand and shaking them rhythmically to accompany other instruments. They are frequently used in ensembles alongside instruments like the guitar, bongos, and trumpet, adding a lively and festive element to performances.
