Is there somewhere an audio sample to listen, on how would a melody sound using fitted/added  'quarter-tone'  keys  ?

-Found an article about a composer trying to build a keyboard with such extra keys...-

Edited- added:  Sorry. Dumb me; should had searched for it before asking...

Here's another on guitar:

 

Bela Bartok used quarter tones - quartets 3 onward.

One of my favourite examples is The Don Ellis Orchestra - he had a trumpet made so he could play quarter tones. The sound just makes me smile every time. Check out Electric Bath.

And here is a 31 tone guitar

 

Here is a fascinating (and slightly bizarre!) documentary on microtonal music: http://thesonicsky.com/video/sonic-sky-introduction/

Being pretty deaf, semitones are the closest I can differentiate and even then, on the lowest string, I can only really do full tones. Quarter tones are wasted on me.

The documentary might still be worth watching as it is very visual
