I am trying to prepare a lecture on scales.

If a is say 440 Hz and r is 12th root of 2

then the usual equal tempered scale would be
a
ar^2
ar^4
ar^5
ar^7
ar^9
ar^11
ar^12 = 2a

What if we change r to 7th root of 2
and replace the powers 2 4 5 7 9 11 12 by 1 2 3 4 5 6 7?

I expect it will sound nonsensical but I really dont know...

I want to show these kind of experiments on the computer. Is csound is a
good starting place to try?

Are there any toots/templates etc for such?
Also which opcodes should I concentrate on?

[For me its been a few days of rummaging around and Ive got out a sine
wave. I expect that the actual code will be about 3-4 lines for an
instrument and 2 lines for a and ar^2 after which I can fill in the blanks.
So for a csound expert it should be 5 minutes. Yes I am being a bit lazy in
asking :-) ]
