CALL of Duty: Black Ops 6 is here, and if you’re already playing the campaign, you may have come across the piano puzzle in the safehouse.

Cracking the piano code is part of a longer puzzle chain you need to solve in COD: BO6, so here’s what you need to do in our piano puzzle solution.

Right across the piano in the music room, you will find a blacklight torch you need to pick up from the table.

Activate the blacklight and use it to check the wall above the piano, where you will find the first clue to solve the puzzle.

There’s the number 1 followed by a musical note written in Cyrillic script, “Ми”, which corresponds to the note E on the piano.

There’s also an arrow pointing to the next clue. Make sure you look around the room with the torch to discover all five clues.

If you’re struggling to find them all, or if you just need a list so you don’t have to memorise or write them down, we’ve got you covered.

Call of Duty: Black Ops 6 piano puzzle solution

Here’s all five notes you need to find, in the correct order and with their corresponding notations in English on the C major scale:

1. Ми (Mi or E)
2. Ре (Re or D)
3. Си (Si or B)
4. До (Do or C)
5. Ре (Re or D)

Now that you have the five notes, all you need to do is play them in order on the piano using the white keys.

If you don’t know how to play the piano, you can use your blacklight to reveal the same Cyrillic notations above the piano keys.

If you play the correct sequence of notes, a secret door will open to the right of the piano.

The door leads to the basement where you will find another puzzle to solve.
