After a year of play time I have this is the best only classical music game out here .There are 50 free pieces and the rest is paid but in the game there is a master tour which gives you free jewels ( when you cleared each pieces) to buy premium stuff in game .If you tend to buy something in game I recommend buying the Prestige (7 days ) because it's the cheapest and it's unlock all pieces permanently even after the prestige period ends (if you clear at least one piece in each pack) with some other benefits.
