The fish who first crawled on to terra firma must’ve felt confused

The first sound they heard was rhythm

The rhythm of the waves

The gentle sshh of ebb and flow, perhaps a stormy cataclysm

And the fetus in a mother’s womb

It was rhythm too that it first heard

Heartbeat, ba boom, ba boom, ba boom

Both a rhythm and a tune.

We’re surrounded by rhythm, heard and not heard

Felt and not felt. Day night, season

The movement of Mother Earth around the sun

Hurtling through space with no apparent rhyme nor reason

Each center of spiritual power

Flowers within, each with their own rotational speed

And sounds, rhythmic sounds that indicate wellbeing

From seed to flower, flower to seed.

Charlie Parker alone based many songs on its chord progression, e.g. "Moose the Mooche". Gary Larson referenced the song in the Far Side.
