Task: Question Answering
Input (English): Passage: South Indian music and dances such as the Kuchipudi and Bharatanatyam styles are popular in the Deccan region. As a result of their culture policies, North Indian music and dance gained popularity during the rule of the Mughals and Nizams, and it was also during their reign that it became a tradition among the nobility to associate themselves with tawaif (courtesans). These courtesans were revered as the epitome of etiquette and culture, and were appointed to teach singing, poetry and classical dance to many children of the aristocracy. This gave rise to certain styles of court music, dance and poetry. Besides western and Indian popular music genres such as filmi music, the residents of Hyderabad play city-based marfa music, dholak ke geet (household songs based on local folklore), and qawwali, especially at weddings, festivals and other celebratory events. The state government organises the Golconda Music and Dance Festival, the Taramati Music Festival and the Premavathi Dance Festival to further encourage the development of music.Although the city is not particularly noted for theatre and drama, the state government promotes theatre with multiple programmes and festivals in such venues as the Ravindra Bharati, Shilpakala Vedika and Lalithakala Thoranam. Although not a purely music oriented event, Numaish, a popular annual exhibition of local and national consumer products, does feature some musical performances.The city is home to the Telugu film industry, popularly known as Tollywood and as of 2012, produces the second largest number of films in India behind Bollywood. Films in the local Hyderabadi dialect known as Deccani film industry, Deccanwood/Dollywood are also produced and have been gaining popularity since 2005. The city has hosted international film festivals such as the International Children's Film Festival and the Hyderabad International Film Festival. In 2005, Guinness World Records declared Ramoji Film City to be the world's largest film studio.
