The Key Finder is totally free and embedded into almost every song page. Once you have defined your personal vocal range, the Key Finder will "magically" tell you how the selected song will fit into your vocal range in every key, and then offer suggested keys that stay within your vocal range. Use this tool often. Your vocalists and your congregation will love you for it! Read more about the KeyFinder in our blog post, How To Match Your Vocal Range To Any Song With The KeyFinder.
