Crazy 8ths creatively combines music education with popular card games-played by reading notes rather than numbers. Beginners can easily master Go Fish and Old Maid, while more advanced players will love the fast and furious fun of PIG and Crazy 8ths. Anyone can join in by using the cheat sheet card. The deck contains 56 musical notation cards covering a two-octave range from bass C to treble C, with rests, triplets, and repeats thrown in. A 28-page book provides rules for 10 popular card games. The teacher's kit contains four extra decks of cards, allowing up to 45 students to play at once.
