Did you ever consider setting your family tree to music? How about musically reciting the members of the family tree for the past 9 centuries? And then doing that for multiple families?
That is what Helavas (professional genealogists) do in in ten districts of Karnataka, India.
An article by Amoolya Rajappa in TheWire.in web site describes the lives of the Helavaru community, a unique semi-nomadic tribe credited to have maintained documents containing the genealogy of several families in ten districts of Karnataka:
“It is believed that Helavas started practicing from the days of Basavanna, a 12th-century social reformer who rebelled against caste hierarchy and gender discrimination. Ever since they have carried on the practice of visiting households and narrating ancestral bloodlines in a lyrical fashion.”
