Overview
- The correct sequence matches the notes "CDDF AFG FGFGA CDD" shown in the music room beside the Red Tower.
- Fifteen red buttons are scattered across Buried City, with routes starting at Plaza Rosa and ending at the Red Tower now mapped in detail.
- Pressing all buttons in the specified order unlocks a loot room and triggers music with visible fireworks.
- Rewards include legendary guitars along with other musical items such as shakers and recorders, according to the published walkthroughs.
- Multiple reports note that button presses are server-side, so a single out-of-order press by any player resets progress and often forces a fresh raid.
