Disappearing Act(ion)

First I was a stick
And then a violin
At last, the bow disappeared
There were no more hands
Shadows and breezes played me
The dreams of mice played me
Until my wood was dust
And my music was whorls
Like smoke in spaces
Now a storm has driven
All my dust to letters
First I was a stick
I am now black markings
And you became my music
All the bows have shattered
