OK I know that there are some of you experts on this...

I've always wanted one, but they have always been 'rustic', looking as if they fell out of the south end of a north headed donkey. So I found a really pretty one the other day.

It has 7 steel rods.

I don't really care about an absolute pitch.

I want to know how the relative tunings are set up, ie. what scale, how arranged, etc.
