Hi, been trying for around an hour and a half with a maker that doesn't have the quest cause my main already has it and other than singing a song and tossing around red musical notes I got nothing else. Then my friend on her main char clicked on it and she got white musical notes and the message "You're playing the Bone fiddle" so maybe trying after doing the quest will trigger the achievement. I found someone to do it for me on his main but it'll be tomorrow. So see you later to update this answer.
