The word Korvai means to compile, join or thread together. Korvais are adavus when set to a particular Talam (Rhythm) and Kalam (speed) and usually concludes with a Theermanam. Dancer Mrinalini Sarabhai says “If we consider ‘Adavus’ as beads, ‘ Talam’ is the thread and ‘ Theermanam’ is the final knot we tie to finish the garland.” Jatiswaram and Tillana are pure dance pieces, where many such korvais are joined together.
Following video is an example of Korvai
We begin with six walking steps. The basic walking steps are called Chalam. To walk, first the body takes a slight dip, while it lifts one feet. Then place the lifted feet forward on the heels. This time body will rise.
After the walks are completed we do the fifth step of Tatti metti Adavu (taka jham tari taka ta). Followed by a step which is similar to the eleventh step of Teermanam Adavu (tai tai tai tai dhit dhit tai). This is repeated both to the left and right.
Then followed by the Tatti Mettu adavu second variation(Ta ka jham tari taka ta ha). Repeat it on both sides.
Also taka jham tari taka nam tari is also done as Ta kita ta kita (similar to Trishra jati Adavu) on both sides. Lastly Ta ka jham tari is a full sitting and Ta ka nam tari is a turn. Such turns are called Bhramari. And what you see here is Ekapada Bhramari.
