Answer:
I begin and have no end. Eventually I will be the end of all that has begun.
A hole in a pole. Though I fill a hole in white I'm used more by the day and less by the night
I begin and have no end and I end all that begins. What am I?
I am black and white. I have strings I have keys. I make sound without my lips. I make dough with no flour
I'm not really more than holes tied to more holes; I'm strong as good steel, though not as stiff as a pole.
