9. Bollywood Dance
The unbroken tradition of linking theatre, music, and dance is traceable all the way back to the Natya Shastra (circa 2nd century BCE.)
The dancing in older Bollywood films was primarily modeled on classical Indian dance styles
In modern Bollywood films Indian dance elements are combined with Western dance elements such as jazz, hip hop and modern
The hero or heroine will often perform with a troupe of supporting dancers
Many song and dance numbers feature unrealistically instantaneous shifts of location or changes of costume between versus of a song

10. Bollywood Dance
Numbers are often staged in natural surroundings or architecturally grand settings. This staging is referred to as “picturisation”.
Sometimes a song and dance is worked into the plot, so that a character has a reason to sing. Other times the numbers are an externalization of the character’s thoughts or events that have not occurred yet in the plot of the movie and are a dream sequence.
Song and dance scenes used to be shot in Kashmir but due to political unrest scenes are now often shot in Switzerland and Austria.
Bollywood films use what is referred to as an “item number” where an attractive female, often unrelated to the main cast and plot, performs a catchy song and dance number in the film.

11. Bollywood Dance
In modern films, item numbers may be inserted as discotheque sequences, dancing at celebrations, or as stage shows.
For the last few decades Bollywood producers have been releasing the film’s soundtrack, as tapes or CD’s before the main movie release hoping to draw in audiences.
Music videos have are also released featuring a song and dance from the film.
Lyrics of the songs often include poetry about the love story of Krishan, Radha, and the gopis. Many lyrics compare the singer to a devotee and the object of his or her passion to Krishna or Radha

12. Costumes
Clothing and costume are an extremely important element of Bollywood dance.  To a very great extent it will determine the "feel" that the dance will have in the film. 

13. Eroticism and Bollywood Dance
It was clear that an element of eroticism was required for commercial success; however the puritanical nature of Indian society would not tolerate the heroine behaving in any immodest way.
Three formulas developed in order to fulfill this requirement, these were the rape scene, attempted seduction, and the item number.
The rape scene has fallen out of fashion, but from the late 1950s through the 1970's it was an essential element for any Bollywood film and was used to establish a villain.
In a seduction scene, the vamp, would attempt to seduce the hero by way of her song and dance.  The hero would not succumb to the charms of this vamp, thus allowing him to marry the heroine.  This approach was especially convenient for producers because they could introduce as much eroticism as the censors would allow, yet the hero's rejection of the seductress would always be considered a testament to the powers of traditional Indian values.
The artistic high point in the delivery of eroticism in Bollywood films was the development of the "item number".  A secondary girl (known as the "item girl") who is able to act, sing and dance in an erotic manner, is brought in often for only one piece.  This introduces the erotic element, yet maintains the heroine's modesty.

14. Eroticism and Bollywood Dance
The cabaret scene is probably the most significant artistic and commercial example of the Bollywood dance.  It may be considered to be the first truly 'Bollywood" form.  Where previous item numbers might have utilized traditional dances, the cabaret dance was unique to the cinema. 
Although it is truly Indian, it does draw upon pre-existing elements, many of which were drawn from Western "modern" dance forms of the 1960's.

15. Eroticism and Bollywood Dance
The most famous item girl is Helen Jairag Richardson, of mixed Anglo-Indian-Burmese descent.  She started dancing and acting in the 1950s, and by the 1960s was the undisputed queen of the item girls.

16. Eroticism and Bollywood Dance
By the 1970s, item numbers were going to the younger girls.  By the 1980's the downplaying of the item girl from the standard formula, along with Helen's age, put her career on the rocks.
Today her career has begun to turn around as she is making the transition from "item" roles to elderly "mother / mother-in-law" roles.

17. Eroticism and Bollywood Dance
The more relaxed attitude toward eroticism in modern films has led to cinematographers not having to rely upon a secondary item girl in order to maintain the heroin's modesty. 
Modern audiences seem comfortable with the heroine dancing very suggestively, where previous generations would have considered this to be scandalous.
