In general, there are two types of Philippine traditional folk dance. The first one reflects the influence under the Spanish occupation and the other, the country's profuseness of tribes that offer their own tribal dances. The music that incorporates the former are mostly bandurria-based bands that utilizes 14th string guitars. One example of such type is the Cariñosa. A Hispanic Filipino dance, unofficially considered as the "National Dance of the Philippines". Another example is the Tinikling. While native dances had become less popular over time, a revival of folk dances began in the 1920s. In the Modern and Post-Modern time periods, dances may vary from the delicate ballet up to the more street-oriented styles of breakdancing.
