Accordion - Games, Puzzles & Learning. A beautifully crafted 18cm wide miniature version of the real thing, made of tough plastic with canvas-type bellows. The number of keys has been cut down to make it easier to play, but it can still be used as a serious instrument, and even with no knowledge or practice its effect is not unpleasant. The basic instructions enclosed teach how to play scales and a few simple tunes. After that, practice helps.
