CARNATIC BASICS - 11

Poorvacharyas have compared the Saptaswaras to the sounds of birds and animals which is shown below-

Sadjam----------The sound produced by peacock
Rishabam----------The lowing of cow
Gandharam--------The bleat of the goat
Madhyamam------The cry of heron
Panchamam-------The note sounded by Kokila
Dhaivatham-------The neigh of horse
Nishadham--------The yelling of elephant

STARTING FROM SADJAM EACH NOTE IS HIGHER IN FREQUENCY JUST AS THE SOUNDS OF THE ANIMALS AND BIRDS MENTIONED.

the bleat of a goat is higher in frequency than the lowing of a cow.

similarly the cry of a heron is higher than the bleating of a goat
