A giant piano is an oversized version of a traditional piano, often designed for entertainment or artistic purposes. These pianos can be found in public spaces, such as parks or museums, and are typically made for people to play with their feet or hands. They are visually striking and attract attention due to their large size and unique design. One famous example of a giant piano is the Big Piano featured in the movie Big, where the character played a tune by stepping on the keys. Giant pianos can also be used in promotional events or as interactive art installations, encouraging creativity and engagement from the public.
