Why do Indian movies intersperse so many songs and dances?

With the Indian culture, the Indian song has its unique style, including its more than the usual seven-steps of the twelve-steps of the tone is even more difficult to sing, that is, the kind of song a song sung behind the back of the support of the high and low different long tone. As we all know, India is a Buddhist country, religious devotion to a certain level, and the origin of their songs and religion-related, their government is to encourage the shooting of song and dance theater, one for the faith, the second in order to protect the traditional culture. India is much more thorough in this regard.

Many Indian film researchers have suggested that the song-and-dance tradition of Bollywood movies may have originated in the worship of Shiva, one of the most important Hindu deities, and is a reflection of the Indian people's devotion to the 'king of dance'. This begins with the Persian community and Persian theater in India. Before the creation of talkies, the most common form of theatrical entertainment in India was watching plays in Persian theaters. The source of today's Indian movies that dance at the drop of a hat is in these Persian-run theaters. Most people of Persian descent in India were not Muslims, but rather Zoroastrian (aka Zoroastrianism, Zoroastrianism) congregations. They migrated from Persia to India in the 8th and 10th centuries to escape persecution by the Arabs who conquered Persia, and still maintain the Zoroastrian faith.

For literate upper-middle-class Indian audiences, the Persians, who controlled the printing industry in Bombay, would distribute scripts to audiences of all races so that they could understand the plot. Let's say if they chose to perform a play in Marathi, they would distribute scripts in Urdu or Hindi, the major Indian languages, to the audience of other ethnic groups.

For the illiterate and illiterate masses of India, the fast-paced Indian songs and dances, with their exaggerated but expressive performances, became a delightful and enjoyable experience for all the languages spoken in India, and served as a link between the languages and all the audiences. Particularly after the 1870s, some Persian theaters moved from India's major cities to wider geographic areas, such as towns and villages, and evolved from fixed city theaters to traveling theaters, where the need for exaggerated movement and lively music was even more important to capture the attention of the audience in the face of inadequate equipment.
