Anyone got any pointers on how to get past the mirror Gallery on Kells Fall? I’ve found 4 notes but can’t compose a melody with them… I‘ve tried playing the opposite side on to each one on the organ (because mirror) and trial and error but nothing sticks. Unless I am missing a small crevice somewhere I can’t progress further anywhere in the mission either. (I’ve resonated the melody in the hall to the right of the organ and taken note of the notes outside as well)
