 The Louisiana Purchase proved to be one of the shrewdest business pacts in the entire history of the United States. The purchase doubled in the area of the country and provided territory from which fourteen new states were created either wholly or in part.

Most children have an interest in learning to play a musical instrument at one point or another during their growing-up years. Parents need to take advantage of that urge to play when it appears. Some very small children become intrigued with music because they see their parents or their older siblings play. The Suzuki method of instruction capitalizes on that early willingness to learn by involving the parent and the child in the child’s instructions. Elementary-aged youngsters often are exposed to stringed instruments or band instruments in their school music classes. Because kids like to do what other kids do, parents who are not musicians themselves can take advantage of both instruction and enthusiasm. It is at the middle school level, however, that peer pressure can really work to the benefit of parents who want to hear the sound of music around the house.
