Hello Kalle!
It is what my score called for but am interested in the properties of
the Nyquist freq. The piece should just have the equivalent to sines at the
odd harmonics, i think, can you make a version?

I would like to hear this. The chord doesn't just sit there anyway but
should have a fair amount of movement in it. Walk around while you have it
on BTW
