The Sound Of Rain

I have almost forgotten
The sound of rain.

Eyes must now calculate
By size and quantity
Of drops on spattered panes
Whether the rain
Falls delicate as fingernails
Or coarse as gravel.

From the geometry
Of spreading rings
Within the birdbath
Eyes must report
Whether the music plays
Pianissimo or forte.

I smell the rain
Mixed with the summer's dust,
And on my hand can catch
The coolness of a shower.

But for my ears
The rainy season's over.
