This achievement is for playing the piano with two other players. It is supposed to work both online or offline with three controllers, but I did it online with two other human players.

Level: Manoir Moucharder
Characters: One player must be The Cleaner, others don't matter. You probably don't want The Redhead in there, messing guards up.

What you want to do is reach the piano room, in the center of the house on the bottom floor, and it doesn't matter if you sneak there or just bust in through the front door. Afterwards, you need the guards to go back to their regular positions in an unaware state.

At that point, The Cleaner stands on top of the cop playing the piano to stun him and the other two players take up their positions on the "top" of the piano, as well as the "bottom." The Cleaner is already in position for the "left" part of the piano, where the keys are.

Before you start playing, wait for the cop that patrols through this room to just have passed by (he comes in through the north door and leaves through the east), then get into position and count down 3-2-1 and then each player holds their respective directions - right for the guy in "left," up for the "bottom" and down for the "top." You will notice that each player is playing a different part of the song and that they come together to form a song. (It is unconfirmed if you actually have to take different positions or if all players can be by the keys, but we did it this way.)

Keep holding your directions until the achievement pops. The Cleaner will constantly stun the piano cop each time he wakes up, without him bothering you and you should have ample time before the patrolling cop comes back. I've seen the devs post on the Steam forums that the timing is very important and that the music will stop after 60 seconds and the players must then walk away from the piano to get the achievement, but none of that applied to us. We started out pretty out of sync (the bass notes sounded retarded), the music didn't stop and we didn't have to walk away for it to pop.

Thanks for K4rn4ge for coming up with The Cleaner tactic and MysticWeirdo for being our third piano player.
