In describing the bamboo wind instruments, Marak shows how tribal lore elevates the material mundane, as the music produced becomes "imitations of wind passing through holes bored by a bumble bee in a bamboo interknot
. ..." Material culture not only serves for practical usage in their daily life, or as the manifestation of a knowledge system, but extends to the religious, the ritualistic, and the artistic.
A part of the chant is translated as follows: The sisters Doni and Ramsi, while fishing in the stream failed to catch any fish and prawn, but a piece, an interknot, of wake bamboo got into the bamboo net of each.
A large, mature bamboo is cut above two knots, retaining an entire interknot. The hollow of the interknot functions as the hollow of the drum.
