Then there's meter. I assume when Fred Miller said rhythm, this is what he meant. I am inclined to agree with him when he said " a melody without rhythm is nearly inconceivable", more important than rhyme, in my mind, when it comes to music. Of course you can play around with these things just for fun:


There once was a man from Japan,
Whose poetry never would scan'
When asked why 'twas so
He replied "I don't know,
But I always try to get as many words into the last line as I possibly can!"
