I hope you don't mind me tweaking your poem a little...
Piano:
Melody keeps go on and on;
I keep playing
Even though the hall is empty,
The audience gone.
I keep playing;
candle flame keeps dancing,
the only reminder of time;
All else is stopped now
For this moment is
forever.
And as I read notes,
the melody goes on and on
Music lives within myself,
Sad and beautiful
Just like, life itself.
And I keep playing every night
Until my eyes fall asleep...
I continue, ever will I suffer;
This is all I will do every night
Until I find you there, listening to me...

Noor, this is just a suggestion. You can choose some, all, or reject them all. I love this piece and realise English is not your first language, so I hope the lines translate alright.
