Types of Growl

Sounds get trapped in cool, dense air.
Tilt your head and close your eyes
If you can both see and hear.

If you can’t hear, touch the ground.
If you can’t see, you know this
And have no need to be told.

Change moves through the world in waves
That are there and not what’s there,
And what is there shapes the waves.

What is there? A kind of dust,
Points, packed waves near to rest,
Which the next waves, which aren’t them,

Shake in arcs that leave some ghosts
Of their own for the next waves
To shake through. Waves build on waves,

And not one wave quite the same,
Not one not at all the same
As the rest. There. What was that?
