According to Emmie te Nijenhuis, a professor in Indian musicology, the "Dattilam" section of "Brihaddeshi" has survived into the modern times, but the details of ancient music scholars mentioned in the extant text suggest a more established tradition by the time this text was composed. The same essential idea and prototypical framework is found in ancient Hindu texts, such as the "Naradiyasiksa" and the classic Sanskrit work "Natya Shastra" by Bharata Muni, whose chronology has been estimated to sometime between 500 BC and 500 AD, probably between 200 BC and 200 AD.
