The "Ta hata jumtari ta" Adavu, is named after the syllables that are used in the practice of the Adavu. This practise is common amongst most lineages of Bharatanatyam.
The Adavu is a combination of various movements. It has the 'di, di tai" action with the Tattu and Naatu, from the Muktaya adavu, it also has a "Kudittam", a jump onto the balls of the feet. It technically can be placed under both categories.
