Hindustani music

From listening to this video: http://www.youtube.com/watch?v=KIM6eQthg_E it is clear that there is heavy inflluence in hHindustani music from vocal ornamentation. It sounds like there could also be a drone featured in this song which is also a classic feature of Hindustani music. The string instruments also play a large role in creating classic Hindustani sound. By listening to this piece you can hear the raga, which is the ascent and descent in pitches in Indian classical music. Its like a scale. The tabla in this piece creates the rhythm for the piece and allows the traditional Hindustani elements to come forth in the song. This style of Hindustani music is called tarana which creates a good mood and typically features strong vocal ornamentation.
