I considered songs about pie, but there really aren’t that many.  So instead, to represent the concept of “Pi”, songs that involve circles.

The wheel is a circle, and the sound of this song has always felt very circular to me as well, the lyrics going around and around.

Very Circular!  Garba songs always are.

And drums are circular

And the moon is a circle

And because the moon is a circle, so is the Karva Chauth tray

Just for kicks, a fanvid!

And finally, (just for Claudia), Jab Harry Met Sejal!
