Sri Lankan Music History
Our ancestors developed art & sound from nature. This is why cave paintings showed animals and the environment. Music started from imitating the sounds of birds & other wild animals.
The North Indian Music notes of Sa, Ri, Ga, Ma, Pa, Da & Ni were supposed to be the imitations of the sounds of Peacock, Cow, Goat, Tern, Kowula, Horse & Elephant.
Music was not only used for entertainment. They got it involved in their day to day life as well. For example, still ‘Pal Kavi’ a form of Folk poetry used in rural arrears when guarding a farmer’s crops.
