The players will have to "create" some musical score with the help of some cards and following the musical rules. No need to know the music or to sing with Rythm 'n' Play! Follow the rules of the flat notes or the sharp notes to place the cards you draw. You have to use a Rythm card to draw some Play cards (maximum 4 cards). If during the player's turn the last Play card played is his, he could continue the musical score or win it.
