While this text can be appreciated by those who have considerable music background and knowledge, it is designed for those with little or no musical background. For that reason, discussion of musical concepts and details has been limited. However, it is impossible to produce a text about music without some musical discussion. Consider it somewhat like visiting a foreign country where the language and customs are different, but in order to more thoroughly enjoy your visit, you need to become a little familiar with the language and some of the customs.
