It's just a joke but if you want this is a version of my os that uses the keyboard like a piano
(only on real hardware)

Do4= q
Do4#=2
Do5 =z
Do5# =s

Ah yeah you have to keep pressed the right shift

very cool! I can use it to tune my guitar

It has still a little bug (I used some wrong frequencies or I put them in the wrong position).Now I'm going to implement the Pulse-width modulation method in order to make complex sounds

I found an old tutorial written in DOS era, but the result of that techniques is very nice. The voice of a person can be head without lots of problems. I'll post a version of Smile with an intro sound.
