No word remains with me
Long enough to call my own
And as soon as it is repeated,
It is forever gone...

If it is my intention,
I might strike the proper note
And set the air quivering
With a heart-ache's antidote...

But love has wings to fly,
Fluttering things take take the sky,
Scarcely a moment on Earth
Dabbling the air with mirth...

Joy will soon run away
And you cannot capture it again
But you may hold in your palm
A feather pricked today...

If love seems out of sight,
Recall a tune or a word,
Sliding down an aura of light,
A melody coming from above...

Romeo Della Valle
