The game intends to let players not know who are musicians or spies, and they have their hidden agenda to trap the villagers or attack the spies to win, but they may get the wrong targets or innocents. Spy is expected to put wrong notes into the scale while musicians are trying to fix it while putting the right ones within a limited time period. To achieve it, spy can fake others and musicians need to find out the spy to prevent her from disruptive actions in the limited time. This game aims to provide an entertaining way for players, no matter if they have knowledge in music or not, to be exposed to music. They can learn about the music scales, i.e. what music notes are contained in the scale.
