Music and Magic in Middle Earth

[Boromir88]

As I said of Boromir's horn, it is probably the power behind the one using the mirror which makes it work. Galadriel is one of the most powerful individuals in Middle-earth, as well as the mirror's owner (creator?), so she can make it work for her -- perhaps like Sauron and the Ring? Only Galadriel can bend the Mirror to her will, and only Sauron can bend the Ring to his?.

Very interesting thought Encaitare, it makes sense, and I like it .
