The tinklings of some vigilant guitars
Of sleepless lovers to a wakeful mistress,
And cautious opening of the casement, showing
That he is not unheard; while her young hand,
Fair as the moonlight of which it seems part,
So delicately white, it trembles in
The act of opening the forbidden lattice,
To let in love through music, makes his heart
Thrill like his lyre-strings at the sight; the dash
Phosphoric of the oar, or rapid twinkle
