The Right Instrument for Your Child: A Practical Guide for Parents and Teachers

The authors started with "why do so many kids give up music?" They concluded that it was usually because the kids started with the wrong instrument. For example, some people have a difficult time doing two or more things at once. So piano might not be the best choice. Somebody quiet and soft-spoken might not be best fitted for trumpet. Somebody small might not be the best fit for a tuba. You might not agree with all their conclusions, but it does give a nice, systematic framework to ask questions and consider answers for yourself and kids.
