CoD: Black Ops 6 Piano Challenge - How to Complete
The BO6 Piano Puzzle is a hidden challenge in the Call of Duty: Black Ops 6 campaign safehouse, The Rook. Playing the correct notes opens a concealed passage toward a locked bunker. It is one step in the safehouse puzzle chain.
Playing the correct sequence opens a hidden door beside the piano. The stairs lead toward a locked bunker; opening its inner door requires the separate boiler puzzle.
This guide will walk you through finding the piano, decoding the puzzle, and unlocking the secret basement in Black Ops 6.
What Is the BO6 Piano Puzzle?
The BO6 Piano Puzzle asks you to press five marked keys on a piano in The Rook safehouse. A blacklight reveals the numbered clues around the room and the matching labels above the keys.
The numbers on the walls show the order. Match each symbol to the label above a piano key; you do not need to work out a musical melody.

Where to Find the BO6 Piano Puzzle
The piano puzzle is located inside The Rook safe house, an interactive hub that serves as the main hideout between missions in the Black Ops 6 campaign.
How to Find the Piano Room:
- The piano room is on the ground floor of the safe house.
- Look for a room directly across from the white kitchen.
- Pick up the blacklight from the table opposite the piano.
- Switch it on to reveal numbered symbols on the walls and labels above the piano keys.
How to Solve the BO6 Piano Puzzle
The BO6 piano puzzle opens a passage beside the instrument. Use the blacklight to read the numbered wall clues, then match them to the labels above the piano keys.
Enter the fixed sequence below to open the concealed door. You can then follow the stairs to the bunker door, which also needs power from the boiler puzzle.
Use the Blacklight to Reveal the Code
- Equip the blacklight and scan the walls around the piano room.
- You’ll notice glowing symbols appearing on the walls, each with a number next to it—this indicates the correct order for pressing the piano keys.
- The fixed order is Mn, Pe, Cn, Ao, Pe. The variable code comes later, at the bunker keypad.
Match Symbols to Piano Keys
- Shine the blacklight over the piano keyboard — each key has a hidden symbol above it.
- Find the piano keys that match the symbols on the wall.
- Play the piano keys in the correct order, following the numbered sequence from the blacklight symbols.
BO6 Piano Code:
Play Mn - Pe - Cn - Ao - Pe in the numbered order:
- Press the key marked Mn first.
- Press Pe second.
- Press Cn third.
- Press Ao fourth.
- Press Pe again fifth.
Once the correct sequence is played, the puzzle will complete, and a hidden door will open.
What Happens After Solving the Puzzle?
After you play the code, a hidden door next to the piano opens. Follow the stairs down; the inner bunker door remains locked until the boiler generator is running.
To reach the bunker puzzles beyond the stairs, you also need to:
- Start the generator in the separate basement boiler room to power the locked bunker door. Once inside, use the blacklight on the keypad and solve its variable code.
You can solve the boiler puzzle before or after the piano puzzle; both are needed to access the bunker corridor.
Why Solve the BO6 Piano Puzzle?
The piano puzzle is part of a larger sequence of hidden challenges in The Rook safe house. Completing it grants players access to:
- The hidden stairs beside the piano and access to the bunker door.
- Progress toward the separate keypad, computer, radio, and safe puzzles.
- The chance to explore The Rook’s former black-site rooms.
If you’re aiming to uncover every mystery hidden inside The Rook safe house, solving the BO6 piano puzzle is your first major step toward unlocking its biggest secrets.
Conclusion
The BO6 piano puzzle opens a hidden passage in The Rook safehouse. Use the blacklight to match wall symbols to piano keys, then play Mn–Pe–Cn–Ao–Pe. Start the basement generator to open the inner bunker door; the keypad puzzle comes afterward.
For those looking to 100% complete The Rook safe house puzzles, this is a crucial first step. Follow the newly opened stairs, power the bunker door, and use the blacklight again for the keypad.
