Composing works of art

I love these pictures of Billie. This is how she is 98% of the time. She's really very happy, enthusiastic and loves everything and everyone. Here she is composing her own music. She plays a few notes, then thinks about it, then plays a little differently and then puts her pencil to her mouth and then says "Yeah! That's it!" and scribbles onto her paper.
A few days later when she goes to play it, it sounds all off. "Mom?" she calls. I turned the paper right side up and now it's all good again.
Billie is taking piano and Jackson is not. Being just 15 months apart they are in the same gymnastics class, the same tae kwon doe class, the same soccer team. Piano is Billie's.
