As you have seen, a Vocabulary allows you to assign descriptive tags to the content. You may also have noticed that only the front page shows multiple pieces of Node Content, that there is only single front page, and that the criteria for Node Content appearing on this front page is simply whether that Node Content has been promoted or not.
So, it would seem that we have a disconnect. For example, what if we want a page to contain some or all (but more than one) of our pieces about healing music? It would seem that there's no way to do that. But there is—Views.
A View is basically a page based on the criteria that you specify. Thus, if your criteria is that you want it to show all of the Node Content with a Taxonomy value of Healing Music, then you will have accomplished the seemingly impossible. Let's do just that!
