It has been pointed out to me, by a poet who has manfully struggled to get the rhyme scheme correct as per the instructions, that there is a rhyme pattern to the rondelet. I don’t know whether it’s the anarchist in me, or simple inattention, but that particular aspect just wafted over me. To put matters right, here’s another rondelet with rhymes and refrains in correct military formation.
They sail away
Their sunset sails golden, leaving.
They sail away,
Bold as gulls, though we’d have them stay,
They smile, embracing their new day,
No backward glance for us grieving,
They sail away.
