Sound keeps looping

[Adny]

Make sure play sound isn't on the "OnStart()", but make it a function. Add an entity collide callback with parent being the Player, and the child being the collide script area. Make sure you have the collision area set so it will not delete on collide so it will repeat whenever the player enters the area (assuming you want that effect). Also, are you tying the piano sound to the actual piano, or to the player?

If you're still having trouble, check out the Old Archives map in the original game so you can see how they did it, and then apply that information to your own.
