Rock, Get It? (It's a Pun)

It’s true I feel the rhythm
Of the earth beneath my feet
For all of glorious creation
Has a tune or primal beat
But should you ever stop
And choose to leave me on my own
Remember:
Just because I rock doesn’t mean I’m made of stone.

Many times I’ve played
My companion only wind
When others of my kind
Their melodies rescind
But forget not my humanity
When I have perfect tone
Just because I rock doesn’t mean I’m made of stone.

If your feet begin to tap
With involuntary life
Or the piercing wedge of music’s edge
Cuts you like a knife
Don’t forget the one
Who endures on his throne
Just because I rock doesn’t mean I’m made of stone.
