I would go to galleries, art shows, museums, and spend time in nature and touring interesting architecture, to feed her love of visual arts rather than go to a class. Expose her to beauty in the world on her own terms and the motivation to develop the technical skill set will evolve intrinsically. I firmly believe that passion is not born in a class setting, but rather in the lived experience. These kids need to strive!
Our neighborhood is particularly good for visual arts and architecture. DS and I will go for at least one walk each week in the neighborhood just to be inspired by the beauty around us.
If she's not the one doing the pulling on the music front, I would let it lie for now. Sure, keep exposing her to great music--concerts, albums, etc.--even let her putter on her instruments of choice. She has a wealth of opportunity and a committed mother who is there to offer love and support.
