When I was around 8 years old, I used to watch Angel Hare every day after school. One day, I received a special episode of Angel Hare called "Angel Hare; Heavenly Harmony" as a Christmas gift from my dad, because my grades had improved. This episode was particularly special because Gabby, the main character, taught me how to play the piano, something that I wasn't interested in but wanted to try anyway. She made it fun!
The episode started with Francis trying to play the piano for a play, which I think was about Noah's Ark, but someone can correct me if I'm wrong. He called Angel Gabby to see if she could help him, and she softly agreed. It was a simple plot.
One of the things that made this episode so cool was that the animation matched the keys of the piano accurately, unlike many other cartoons where the piano key placements are often incorrect. Gabby taught me how to play simple songs like "Twinkle-twinkle Little Star" and some other nursery rhymes. It was like she was guiding me, and I liked that about the show.
