Accordian Songs, also called "Notes", are a collectible item that currently only allow Reshnha to open specific locked doors. Once collected, these songs can be played by pressing shift when no effects are equipped. There are currently only 2 collectible songs, though it seems there may be more added in future releases as Stomidori's letter states that some songs can be used to travel to different locations in the Dream World. Cerasus' Itch.io page also states that Reshnha will need to collect songs in order to escape the Dream World.
