I'm talking about tapping the beat with your foot while you are playing your pipes.  This has been a challenge for me, but I've been forcing myself to do it every time I play and it is getting easier to do.

At first my foot tapping was a lot like my entire leg was moving, then my body, it was pretty silly looking and exhausting.  Now I'm able to just tap my foot and on every other part I will switch which foot I tap (it gets tiring to tap just one foot all the time).
