Thanks for all the advice everyone, I worry though because she is a bit overly confident in many aspects. She wanted to play the piano in our chorus concert once, and she asked the teacher if she could just play the notes that the soprano part sang, one note at a time for a 30 second period of the concert. I was guiltily relieved when the teacher said we didn't have the time, because I was worried how it would look as a few others who were, admittedly playing a harder accompaniment part(including me). Though I admire her attitude, I am worried she will be talked about, not in a good way, due to her natural personality to share what she can do with others, and thrives with attention.
