It also means the meter and rhythm of poems. It's a word I've only seen once before, in the last two weeks while reading Hermann Hesse's second novel, Beneath the Wheel. I used it in this poem, https://medium.com/write-under-the-moon/a-poets-contemplation-on-snow-97c69ce22cfc, which I decided would be my last for a while as I return to my essay roots. And then with all the MPP nonsense on Medium, I decided to start posting free to read content to remove the aggravation from my psyche. It was a very freeing decision. Reminding me why I came to Medium in the first place. You might enjoy the two free essays I've posted so far. They're quite spiritual/metaphysical, other than the portion of the first one that explains my decision, but the method of arriving at it was metaphysical.
