The World’s Most Famous Musical Calculator Player

Chaco Chaco is a popular South Korean Youtuber whose claim to fame is the ability to reproduce popular songs on one or multiple musical calculators.

Calculators are handy when dealing with math, but one particular calculator is actually more popular as a musical instrument. The Egoelife AR-7778 and AR-8001 are designed as instruments and even come with instructions on how to use them as such. But, just like with any other musical instrument, you need talent and practice to produce music worth listening to, otherwise, you’re just using it as a cool toy. That’s what sets Chaco Chaco, a musical calculator artist with over 800,000 subscribers on YouTube alone, apart from pretty much any other musical calculator user.

Chaco Chaco (차커 Chaco) has been producing content on YouTube since 2018, but it was only in mid-2020 that his channel really blew up. That’s when he first started messing around with Egoelife musical calculators, and people loved it. He gained tens of thousands of fans in just a few months and now sits at over 815,000 followers on the popular video-sharing platform.


There are those who consider Chaco Chaco the first true musical calculator artist in the world, but the truth is that others have been doing it much longer than him, even in his home country of South Korea. Then there are the musical calculator artists in Japan, but the truth is that in terms of popularity and notoriety, Chaco Chaco is in a league of his own.


To be fair, the kind of tunes he is able to produce on musical calculators are pretty impressive, and seeing him use up to five different calculators at once in order to produce the desired effect only adds to his aura.


Although South Koreans still make up the bulk of his fanbase, Chaco Chaco has a serious international following, as you can tell by the languages used in the comments on his YouTube channel.


From popular anime soundtracks, to pop classics and even film themes, there’s nothing that this talented artist can’t play on his musical calculators.
