>Sure, but even in western music the chromatic scale is considered to have been exhausted in the 20th century.

Yeah, but by people like Schoenberg, Alban Berg, and the like, or the wilder jazz guys. Not exactly what most people enjoy with a cup of coffee.

>Modern music has moved on to use other notes and sounds and in many cases is not even pitch-centric.

I think that for e.g. electronic, dance, experimental music etc, the chromatic scale/classical harmony/etc. is still a good foundation -- the additional not pitch-centric focus is either in rhythm (which is orthogonal) or in sample/noise-based focus which usually just goes with "if it sounds good, it's ok" kind of approach.

So, not much micro-tonal or other approaches going on in practice.

It's out there if you open your eyes a bit. There is a TON of microtonality in blues guitar playing - they just don't use the $10 academic words for it.

[coldtea]

Well, I'm from a country where lots of folk music is microtonal.

That said, I don't consider the blues guitar playing a major example of microtonic music, $10 words or not. There are some elements, but you can find much more impressive examples in African music for one (part of which could have been inspiration for early gospel/blues musicians).

Have any examples you could link to? I'm very curious to hear what that sounds like.

Just listen to any blues...there are string bends all over the place, and many of them aren't traditional western 12-tet intervals.
