a hummed tune

a blade of grass is growing
the winds have changed their course
people are doing headstands
what are they doing that for?

hmm hmm hmm hmm hmmmmm
hmm hmm hmm hmm hmmmmm
hmm hmm hmm hmm hmmmmm
hmm hmm hmm hmm hmmmmm

subatomic explosions
pressure and release
atoms are bunching together
forming a tree

hmm hmm hmm hmm hmmmmm
hmm hmm hmm hmm hmmmmm
hmm hmm hmm hmm hmmmmm
hmm hmm hmm hmm hmmmmm

circle triangle square
a curvy outside contour
steady construction
a solid base and form

hmm hmm hmm hmm hmmmmm
hmm hmm hmm hmm hmmmmm
hmm hmm hmm hmm hmmmmm
hmm hmm hmm hmm hmmmmm

rough around the edges
smooth in the middle
a shape I've never seen or felt
it won't freeze and it won't melt

hmm hmm hmm hmm hmmmmm
hmm hmm hmm hmm hmmmmm
hmm hmm hmm hmm hmmmmm
hmm hmm hmm hmm hmmmmm
