Remothered: Red Nun's Legacy Guide | How to Open the Box in the Music Room

To open the locked box in the Music Room in Remothered: Red Nun's Legacy, you need the Small Key found beside the broken Metronome in the wine cellar. Use it on the locked container on the table in the Music Room to get the Metronome Arm, which you need to repair the Metronome and unlock Moth Manipulation. 

Finding the Small Key

Before you can open the box, you need to reach the hidden wine cellar beneath the Residential Wing. This requires using the mirrors in the Kitchen to reveal a secret passage.

Start by entering the Kitchen and inspecting the mirror. Use Secrets in the Mirrors to reveal another mirror on the left side of the room. Interact with the newly revealed mirror to uncover a third one. Continue examining the mirrors until a hidden doorway appears.

Go through the passage and descend the stairs to reach the wine cellar. You will find a broken Metronome in this area. Look around the device and collect the Small Key lying on the nearby table.

Be careful when picking up the key, as doing so triggers a cutscene and introduces the Bride as a Stalker. She will begin pursuing you, so leave the cellar and find a hiding spot if necessary. 

Returning to the Music Room

Once you have the Small Key, head back upstairs to the Music Room. You may need to avoid the Bride while travelling through the corridors, so use hiding places and wait for her to move away before continuing.

The Music Room is located on the upper floor, near the balcony. Inside, you will find a piano and a violin. A locked box also sits on a table.

If you have not already done so, use Retrocognition on the guitar beside the piano to reveal a memory. This is part of the room's investigation, but it isn't required to unlock the box.

Approach the locked container and interact with it. Select the Small Key from your inventory to unlock it.

Collecting the Metronome Arm

Inside the box, you will find the Metronome Arm. This is the missing component needed to repair the broken Metronome in the wine cellar.

Collect the item, then return to the cellar where you found the Small Key. Interact with the broken Metronome and install the Metronome Arm.

Once the device is repaired, interact with it to trigger the next sequence. This will eventually unlock Moth Manipulation, an important ability that allows you to control groups of moths and use them to remove cocoons blocking doors and passages.

You will need this ability to progress through the Convent and access several areas of the Residential Wing, including the workshop needed to repair the Broken Doll for the Mother Puppet. 

Final Thoughts

Opening the Music Room box is an important part of progressing through the Residential Wing. The Small Key is found beside the broken Metronome in the wine cellar, which you can access by revealing the hidden passage through the Kitchen mirrors. Once you have the key, return to the Music Room, unlock the container, and collect the Metronome Arm. Repairing the Metronome unlocks Moth Manipulation and lets you keep exploring.
