What is the rhyme scheme of the excerpt from "Lochinvar"?
So stately his form, and so lovely her face,
That never a hall such a galliard did grace;
While her mother did fret, and her father did fume,
And the bridegroom stood dangling his bonnet and plume;
And the bride-maidens whispered "'Twere better by far
To have matched our fair cousin with young Lochinvar."
