Sure, the Game Gear Micro may be the latest product from SEGA, but way back in 2007, the company released the Grand Pianist. It’s still the world’s smallest functional grand piano, and yes, it has self-playing capabilities. Measuring just 4mm wide, each one of the 88 keys work just like on a real piano, and there’s already 100 built-in songs (expandable with an SD card).
It weighs approximately 7.9-pounds, and while the keys are functional, all of them are actually synthesized through an integrated speaker. Unfortunately, it was never released in the US, possibly due to its high $453 USD price tag. Despite this setback, the piano sold extremely well in Japan after being released on April 1, 2007.
