So, I started programming and within five hours more or less I’ve developped some things and: it’s possible. The idea is: you have 8 chords in the screen and you choose one of them with the nunchuk stick; when you shake the Wiimote in the vertical direction it will produce sound. With “C” you temporary chhange “minor” chords to “major” ones and vice versa. And with “B” you change the screen chords by others, so you can choose. More or less like Jam Sessions does.

How does it look like?

By now there are only 4 chords and it still is a proof of concept. But after exams I will probably improve it, clean and modularize the code, and release it with the code. It can be a funny thing to show to your friends in a party. I’ve used C language, SDL and libwiimote despite I’d like to try out some SDL bindings like Python one.
