Hi EP
I have sung it in my head a few times (it sounds better that way! I’m not a singer, but I am quite good at poetry).
It does flow very nicely and has a natural rhythm.
The ‘some people say’ line, I think, needs an extra syllable, so I add ‘they’. (Some people they say)
Also ‘contentment’ is a bit clunky.
Other than that it’s really very good!
Unfortunately, I can’t share the tune that I’ve used! I’d describe it as a bit like one of the tunes that you sing at school.
