What is "guayo"

The guayo or ralladera is a metal scraper used as a percussion instrument in traditional styles of Cuban music such as changüí, predecessor of son cubano. Largely replaced by the güiro (gourd scraper) during the 20th century, the guayo is now rare. In the Dominican Republic, the güira, a similar metal scraper used in merengue, is sometimes called guayo. In contrast to Cuba, güiras replaced güiros in the early 20th century.

The guayo is a Cuban percussion instrument. It may also refer to:

• A grater, in the Caribbean
• Guayo River, Puerto Rico
• Guayo Cedeño, Honduran musician
