As you walk through the corridor away from the music department and into the sculpting department, see the sculpture that is different from the rest. Interact with it, then continue on until the final sculpture in the row breaks. Go back and find a door that wasn't there earlier. Interact with it, then move on - a short event will trigger. Go to the door again and interact with it, then continue on.
The achievement should unlock.
