I had a remarkable thing happen in my piano studio. My student Christopher, a composer, has written seven pieces, two of which we have notated in Finale. Composition #7 is really fun to play. I introduced it to Julian who started it and had to wait until we finished the ending. During the weeks that Julian was learning it, another younger student, Olivia, was sitting through Julian's lesson, waiting for her time. I did not realize how intently she was listening. One week later at her lesson she announced, "I can play Christopher's song!" And that is just what she did. Wow, how we influence each other.
If you would like to see the music you can find it on the resource page at this, my studio webpage.
