If you were a 90’s kid then, you most probably might have played the game Mario and be familiar with its theme music. The game was designed by Japanese game designer Shigero Miyamoto and is one of the best selling video game franchise of all time. The game is owned by popular game company nintendo. 

Have a look at this surprising video. A person plays the mario theme music using four calculators. Truly, music is about finding out the harmonies in nature. Its much more than just a musical instrument.
