The game starts with Bugs Bunny standing in front of a stage. Bugs explains that the Tasmanian Devil destroyed the classical music in some old Looney Tunes and Merrie Melodies cartoons, so it's up to the player to conduct a new orchestra to refill the Looney Tunes cartoon background music. Bugs then will teach the player about how to conduct the orchestra.
Playesr must conduct an orchestra to perform at a classic Looney Tunes cartoon. To start the orchestra, players must tap three times on the touch screen, like a real conductor. To make the orchestra perform perfectly, players must tap or drag the notes at the right times; if not the performance meter will go down. If the performance meter depletes completely, the orchestra will be canceled and the game will end. There are four difficulties: Apprentice (easy), Conductor (normal), Maestro (hard), and a fourth, unlockable mode and the hardest one: Looney. This mode is about as hard as Maestro mode, but unlike the other difficulties, the player must play through the intervals instead of just watching them.
Each time the player taps or drags a note, the player will gain a varying amount of points. The amount of points depends on the player's accuracy. There are four accuracy levels in the game: Gold, Silver, Normal, and Miss. The score level, scores, and combos also affects the performance meter, the audience, the cartoon, and the musical grade. There are five musical grades: S+, S, A, B and C. The musical grade can be guessed by the amount of applause when the cartoon ends.
