I`m the sweetest sound in the orchestra heard,
Yet in an orchestra have never been.
I`m a bird of gay plumage `tho less than a bird.
Nothing ever in Nature was seen.
Touch the earth, I expire,
In the water I die,
In the air I lose breath,
Yet can swim and can fly.
Darkness destroys me, light is my death,
And I only keep going by holding my breath.
If I cannot be guessed by a boy or a man,
By a girl or a woman I certainly can.
Can you work this one out?
