Luke actually gently pushed down on one key at a time. He did not bang on the keys. The music he produced was lovely and just flowed. I could tell he was enjoying listening to the music as much as those around him.
Before I knew it, Luke was giving me lessons. He was explaining to me how the keys all the way to the left were "noisy", as if that was the technical term.
Luke even turned the pages of the book as if he was really reading the music. Then he went as far as asking me for a different book so he could play another song. I wish we had the space to have a piano in our house for him to practice. I think there may be piano lessons in his future.
