In Cuba, Arsenio Rodrguez integrated tumbadora into his son groups and created the son montuno sound that significantly influenced salsa. Radios broadcasted bat drums and gained greater international reach. A tuning system for conga and bongo emerged, which allowed Carlos Valds to popularize the use of two congas. A standard percussion lineup for Latin music then developed in New York through Machito and His Afro Cubans: a combination of bongo, congas, and timbales. Mambo became a widely-used term for Latin music in the city.
