Harmonizing a Poem by Palace-Attendant Kuo

High beyond the thick wall a tower shines with sunset
Where peach and plum are blooming and the willow-cotton flies.
You have heard in your office the court-bell of twilight;
Birds find perches, officials head for home.
Your morning-jade will tinkle as you thread the golden palace;
You will bring the word of Heaven from the closing gates at night.
And I should serve there with you; but being full of years,
I have taken off official robes and am resting from my troubles.
