The Twilight Turns

The twilight turns from amethyst
To deep and deeper blue,
The lamp fills with a pale green glow
The trees of the avenue.

The old piano plays an air,
Sedate and slow and gay;
She bends upon the yellow keys,
Her head inclines this way.

Shy thought and grave wide eyes and hands
That wander as they list — -
The twilight turns to darker blue
With lights of amethyst.
