Ballade

Writing in forms really isn't difficult -- not technically speaking anyway -- once you've practised it enough, you can turn your hand to pretty much anything.  But the trick, as you've pointed out, is to make sure that YOU are in charge of the poem, not the rhymes.  A lot of people say that rhyming poetry is limiting, and I just don't think that's true.  There is always a rhyme that suits what you want to say, and if there isn't then you just go back a couple of lines and change another word to make it work -- it's not limiting, but it IS disciplined. 

Many thanks for your lovely comments
