Analysis of My guitar

My guitar plays the tune,
With the accompaniment of my mind.
His every string knows,
the every feeling of my mind.

When my mind is upset,
He produces melancholic tune.
But when my mind is brimming in joy,
He releses mind soothing tune.

He travels with me.
He walks with me.
He sleeps with me.
He is never parted with me.

Sometimes he hangs on the wall.
It is the only time,
we stay in our own world,
with our own activities.

Sometimes I think if I will perishe before him,
will he play flawlessly with other fingers?
If he will perish before me,
Will my fingers play with a strange one?
