How about buying her a DVD set of classic musical movies, like "Singin' in the Rain", "The Sound of Music", and "My Fair Lady"? You could also consider getting her tickets to a local theater that's showing a musical she hasn't seen yet, or buying her a collection of original Broadway soundtracks. If she's a fan of musical theater, you could also consider getting her a subscription to live streaming shows from BroadwayHD or a gift card to a musical theater-themed bookstore.
Or you can get her a star map with the date when she was born.
