A simulated X-ray showing a small brain with the text "SMALL".

The ad opens with a young boy sitting on a couch, holding a video game controller. His brother then appears, holding a tablet and showing a simulated X-ray of a small brain. The younger brother is initially annoyed but then intrigued as the older brother shows him the Simply Piano app on the tablet. They then set up a red Casio keyboard and the younger brother begins to play, guided by the app. The app shows musical notes and feedback, with a checkmark appearing when a note is played correctly. The boy earns stars and levels up, showing excitement. The ad concludes with a split screen showing the app interface and download buttons for the App Store and Google Play.
