 Wowza!
Musical ear or not, Levi could indeed identify when something was off.
And he wasn't imagining the fact that it felt warmer than before, right?
His heartbeat sped up and holding his wand with lumos on it over the keys, he used his empty hand again to stroke across the keyboards. There was nothing particularly beautiful about the way the piano sounded; it was horribly out of tune and the sounds resembled groans more than anything else.
But one stood out the most, almost like it was--releasing air? Or like it didn't belong there at all. It was hard to tell, but it was irregular in a way that the rest of the old keys were not. Levi pressed down on it with his index finger, several times, careful not to overdo it; after all, his strength potion was supposed to last him for half a day and it hadn't even been an hour.
The sixth year leaned in close. The scroll had mentioned a lever, had it not? A lever to open a door, specifically. Quirking one of his eyebrows, Levi used his thumb and index finger and pulled, trying to lift the last key.
