Despacito performed on two musical calculators
by Rob Beschizza from on (#315MX)
Your entry point to It's a Small World's YouTube channel of curiously haunting covers of pop songs performed on bleepty calculators.
That model of musical calculator (are there others?) doesn't seem to be available anywhere; all I found was a dead product page on Ali Express.
Chiptunes not your thing? Here it is on cello, by 2cellos.
