The Musicat has got 72 cards in his box. Who finds the most matching pairs? Who knows the instruments? Who can allocate the sounds to the instruments? This game of pairs, a musical instruments matching card game, is an exciting and interesting memory training game for the whole family. While playing, children and parents get to know all musical instruments 'en passant': from clarinet via timpani to balalaika. These instruments can be heard on the accompanying CD in well-known song melodies. Thus, the different sounds can be memorized quite easily. Apart from the 'classic' game of pairs, the instructions describe many other possibilities of how to play with the cards of pairs and the CD.
