Did you know why bharatnatyam dancers move back and forth in straight lines?

The reason that bharatanatyam dancers beat their feet and move up and down the stage for a full 8-10 seconds or so after a jathi (pure dance sequence) was for a few reasons:

1. To move in the procession when they were dancing outside in a parade like setting.

2. To move back to hear the musicians (who, unlike now, where they sit to the left of a dancer on stage, used to stand and play behind them).

Now you know.
