WE LOVE THIS INSTRUMENT! This toy accordian does exactly as you think it will! It requires no batteries and creates a huge range of notes, tones and is ready to march or serenade throughout your house! ANother caveat for this cute little music maker is the fact that your child is doing cross body work with is excellent in getting both sides of the brain working together! Any diagonal, pushing or pulling that a child does with this instrument is actually facillitating new synapes to be formed as neurons fire between the two hemispheres. So, Tchaikovsky or a little Irish Jig anyone?
