The music room in Gakuren is usually an interior room inside the school/building , not a separate outdoor location. From player clips and guides, it’s a room you reach by going through the school area and checking the side hallways or upper floors rather than the main courtyard.

Quick path

  • Head into the school building.
  • Look for side hallways and classroom-adjacent rooms.
  • If you do not see it right away, check upstairs or any unlocked interior doors.

What players are saying

  • Recent gameplay clips mention that the game has a music room and show players encountering it during exploration.
  • A beginner guide for Gakuran was published recently, which suggests the game is actively changing, so room locations may shift with updates.

Easy check

If the room is not where you expect, try:

  • Rejoining a different server.
  • Looking around the school after spawning.
  • Checking for update-related map changes.

Note

I couldn’t verify a single official map marker for the music room from the available public results, so the exact doorway can vary by version or server.

TL;DR: In Gakuren, the music room is inside the school area, usually off a hallway or upper floor, and its exact spot may change with updates.
