It’s hard to find anyone on the planet who doesn’t know the tune to the first level of the classic Super Mario Bros. Nintendo game. Even in Israel

Last summer, Israeli YouTuber EranAmir–who is online famous for his Black And White In Color piece–traversed the streets of Israel for another creative art project.

He asked 300 passersby to sing one note of music along with his portable piano while he recorded them. He then compiled all the notes to create one harmonious melody on The Human Piano.

Though the video debuted last July, it has only experienced a viral surge in viewership this week, quickly amassing over 100,000 hits, and counting.
