Whenever I read about Indian Classical music or its history, from the earliest books till date, they always mention that the Indian music has melody whereas the western music has harmony. This is very surprising to me because even some of the African music has harmony and we missed it. I have been trying to find examples of it in Indian classical music, but I don't know enough. Here is the earliest example from Hindi film music (based on what they say in books, all I hear is two different tunes overlapping in many places.)
