I'm working on a project of my university (mathematics). I think it would be really cool if I could show that we can make new music systems with new tunes.

So, is it possible to create a keyboard online choosing the frequency of each key?

    Of course it is - all you need to do now is figure out how... which is well outside the scope of this site. – Tetsujin Jan 12 at 18:04
  • Yesterday, I saw a strange keyboard - two sets of buttons - maybe 60 in each. Very modern. Guess it could be a flat electronic version of a squeezebox... Yes, you could, but isn't it almost re-inventing the wheel? – Tim Jan 12 at 18:07

Once you know how to make an online keyboard, it's relatively trivial to make it play any scale you want. You might want to search for existing keyboards people have made that allow microtonal playing, or allow the player to choose the intonation. In fact by searching for those terms, I found two existing ones:

If you are doing an academic project into choosing new tunings, you should be aware that this isn't a new idea. You might want to look into the topic of limits, and some of the existing non-diatonic scales that people have come up with.
