Keralanadanam (Kerala Dance) is a new style of dance that is now recognised as a distinct art form evolved from Kathakali a form of Indian dance-drama. The Indian dancer Guru Gopinath a well-trained Kathakali artist and his wife Thankamani Gopinath who was the first student of Mohiniyattam in KeralaKalamandalam developed a unique structure for teaching and performing classical dance forms of India whose origins are from Kathakali. Solo, duets, dance dramas and traditional folk dances were the material they chose.
Guru Gopinath and Thankamani's dance programs found traditional pieces existing side by side with those modified to present a variety of themes. Their style relied heavily on the angika abhinaya - body movements and gestures - and swatvika abhinaya - facial expressions from Kathakali. The major stance of Kathakali was however changed by Gopinath to a more convenient pose that could still rest well with the tribhanga concept.
Another significant deviation was in aharya abhinaya- (costume mode) where they adopted costumes and facial makeup to suit the role. Thus in a dance on Jesus Christ the dancer dressed like Christ. In social dances the artists wore the dress of labourers, peasants, folk etc. Likewise roles of Sri Krishna, king, snake charmer, hunter had the appropriate attire. For the first time Carnatic music Gopinath rendered compositions used for concerts into dance forms. Unlike traditional Kathakali and Mohiniyattam, a variety of many musical instruments were also added to his presentations.
Even though during his lifetime Guru Gopinath did not give a name to his style after his passing away the movement to give his style a name gained momentum. In 1993, during the Global Conference on Guru Gopinath and Keralanadanam held in Trivandrum, his students gave a Sanskrit definition to this style. KERALEEYA SHAASTRIYA SARGAATHMAKA NRITTHAM- "A traditional creative dance style originating from Kerala."
Keralanadanam can be performed in three ways: Ekamga Nadanam i.e. solo, Samgha Nadanam i.e. group, Nataka Nadanam i.e. dance drama enacting a story. Male female pair dancing (duet) is also a distinct style in Keralanadanam. So also he has extended the dance drama to 5 or six hours long dance performance called Indian ballets.
