Musical Phantom...

Tonight, at exactly 5:30 in a Monzingo Music store.  Every employee, teacher and customer will drop dead, and start listening to the beautiful music floating from the first room on the left side of the hallway.  A ghostly yet captivating sound it will be indeed.  Oddly, it sounds a lot like a violin.  Finally, after 30 minutes, it stops suddenly.  Everyone will begin shaking their heads and looking wildly at each other.  Then the door creaks open and there stands a girl, violin in hand.... Me!
