Inside Bollywood

Bollywood songs, more formally known as Hindi movie songs, are songs featured in Bollywood films, often performed in item numbers.
The language of Hindi movie songs, generally termed Hindi, can be complex. Some songs are saturated with Urdu and Persian terms and it is not uncommon to hear use of English words in songs from modern Hindi movies. Several other Indian languages have also been used including Braj, Bhojpuri, Punjabi and Rajasthani. Occasionally a few lines in other Indian languages are used as well.[1]

The Nine Rasas
A rasa identifies the dominant emotion of a composition (a song or a text). In Sanskrit and Hindi literature, nine different types of Rasas are often enumerated.
Shringar – Romance,
virah: separation
milan: being together
Raudra – Furious
Hasya – Comic, Humorous
Beebhatsa – Disgust
Veera – Heroic, Brave
Karuna – Pathos and Compassion
Bhayanak – Fear and Anxiety
Adbhuta – Wonder and Curiosity
Shanta – Serene, Contemplative
This classification goes back to when the chief patrons of literature were kings and nobles. The filmi songs are however written for common people and thus there are some common themes that are often encountered – songs for children, songs of betrayal and dejection, marriage songs, etc. that ordinary people can relate with.
