Metre

[RiverNotch]

All verse composed of pronounceable words, no matter its constraints, possesses intrinsic meter.
Short syllables, long ones, pauses...
And pressing your lips tightly together doesn't alter this as your brain first perceives a written word as a sequence of sounds (fMRI studies have shown).
Speech is about 200,000 years old and writing 5,000; and you learn to speak/listen years before you learn to write/read.

So, yeah, it's obvious I guess: Life is about dancing.

I remember watching something on youtube from a channel that had pretty good expositions on sciencey stuff I actually knew about that singing may be the natural condition for most talking animals (eg birds), it's just that, unlike birds, humans can't fly to escape their hunters.
