This magical penny whistle looks completely ordinary.

As an action, you can play a special tune on the whistle. When you do, a 5-foot stage appears in an empty space within 15 feet of you. A grumpy imp quartet, with hand drum, pan pipes, lute, and viol, appears on the stage in a puff of sulphur-smelling smoke. The imps play songs of your choice for up to 10 minutes, then they vanish along with the stage in another puff of smoke.

Cursed. When you play the whistle for the first time, you become cursed. While cursed, you can't get rid of the whistle. It reappears in your pocket, bag, or hand at sunset. Additionally, whenever you make a Charisma (Performance) check, also roll a d4. If the d4 rolls 1, the imp quartet appears and starts playing loudly over you until you stop performing, at which point it disappears again.

You can break the curse by submerging the whistle in holy water and then throwing it away. The next person to play the whistle becomes cursed instead.
