Explanation:

Mohiniyattam is one of the eight classical dances of India that developed and remained popular in the state of Kerala. Kathakali is another classical dance form of Kerala. Mohiniyattam dance gets its name from the word Mohini – a mythical enchantress avatar of the Hindu god Vishnu, who helps the good prevail over evil by developing her feminine powers.

• Mohiniyattam is based on Natya Shastra’s lasya style.  It has delicate movements and more feminine facial expressions. The movements are gentle and glide-like. They do not have terse rhythmic steps. 

• It is traditionally a solo dance performed by women after extensive training. The repertoire of Mohiniyattam includes music in the Carnatic style, singing and acting a play through the dance, where the recitation may be either by a separate vocalist or the dancer herself. The song is typically in Malayalam-Sanskrit hybrid called Manipravalam.
