Percy Bysshe Shelley - To Jane

The keen stars were twinkling
And the fair moon was rising among them,
Dear Jane:
The guitar was tinkling,
But the notes were not sweet till you sung them
Again.
As the moon's soft splendor
O'er the faint cold starlight of heaven
Is thrown,
So your voice most tender
To the strings without soul had then given
Its own.

The stars will awaken,
Though the moon sleep a full hour later,
Tonight;
No leaf will be shaken
Whilst the dews of your melody scatter
Delight.
Though the sound overpowers,
Sing again, with your dear voice revealing
A tone
Of some world far from ours
Where music and moonlight and feeling
Are one.

Percy Bysshe Shelley
