Around the room are points where you can find the notes and there order for the song that must be played. For best effect these notes should be different each time the instance is generated. Playing the correct sequence will result in the passage forward being unlocked. Playing incorrect notes results in small group of monsters spawning. The difficulty of these monsters increase with each successive incorrect note entered. To make this an actual trap and not a sp bonaza these mobs reward no sp nor do they have any loot.
