The first lesson I've learned is that no matter what you do in your life you have to figure out your own internal rhythms - I mean what works for you doesn't necessarily work for your friend.
Women hear rhythm differently than men.
Apart from a few simple principles the sound and rhythm of English prose seem to me matters where both writers and readers should trust not so much to rules as to their ears.
On the mountains mistakes are fatal. In politics mistakes are wounding emotionally but you recover. Personally wilderness helps me get back in touch with natural rhythms helps me reflect and in the process restore my creativity.
I use rock and jazz and blues rhythms because I love that music. I hope my poetry has a relationship with good-time rock'n roll.
Children seem naturally drawn to poetry - it's some combination of the rhyme rhythm and the words themselves.
I used to write sonnets and various things and moved from there into writing prose which incidentally is a lot more interesting than poetry including the rhythms of prose.
Rap is rhythm and poetry. Hip-hop is storytelling and poetry as well.
From my music training I knew that some Spanish rhythms apart 5/4 is a time signature used only in the modern era. Holst's Mars from the Planets is 5/4. But if you speak lines of poetry in that pattern you just end up hitting the off-beats. It's only when you add a rest - a sixth beat - that it sounds as it surely should sound.
In poetry you must love the words the ideas and the images and rhythms with all your capacity to love anything at all.
