Answer:
I sit in a corner while traveling around the world. What am I?
My voice is tender my waist is slender and I'm often invited to play. Yet wherever I go I must take my bow or else I have nothing to say.
I am a tool for fairies.
I go up when the rain comes down
Without me everyone would lose their head.
It flows out of the soil, It burns you if it boils, And holds us in its coils, More valuable than gold, As black as it is old.
