Kit, glad to see you took up the challenge with a story of your own. Well done in keeping it within their 1000 word limit.
I read it through and made some comments and a few edits. There were a few changes I made for flow. I also wanted to hear more of the voice of the 4th and 5th grader coming through the words.
I loved how you personalized it with the story of your Dad listening to recordings around the house and conducting the orchestra in “air” baton. ( MY Dad did the same thing to March Music of John Phillips Souza)
Take a look at the changes I made and see if they fit with the way you speak.
When you’re comfortable with it. hit the send button to American Public Media. Yours is a good story as it is quite relatable for other classical music listeners.
