In The 39 Clues One False Note you learn about different famous people (Otherwise known as Cahills) who have made history to a lot of the people on earth.(Unless your Dan of course) Amy is, as Dan calls her, a major brainyach (or Dan's sister).

With Social Services and their cousins after them it's hard to stay hidden. while having to do so many risky things. But they survive, at least for now? Especially in One False Note. Amy and Dan have the privilege to learn Mozart's famous KV617. A famous music peace written by Mozart himself KV617 is played on the glass harmonica.
