Sruti upanga

[5] The instrument was described by Charles Russel Day (1860-1900): The bagpipe here drawn is the Moshuq, or, as it is called in Southern India, Śruti-upanga or Bhazana-śruti.

It is used merely as a drone ; the holes in the pipe are wholly or partially stopped with wax so as to tune the instrument to the pitch desired.

The bag is made of the skin of a kid and is inflated from the mouth by means of the smaller of the two pipes shown.

An enlarged drawing of the reed has been given in the plate, in order better to show its construction, and, as can be seen, the vibrations are controlled by a little piece of wire or fine twine tied roughly round the tongue.

[6]Beatrice Edgerly notes in 1942, similar to Day, that the pitch of the instrument was controlled by inserting wire or bits of silk.
