Because a choir is formed by Mens and Ladies, every section has its range. So, I though that maybe I could create a variety of inharmony linking all the partials of the different harmonic series. I took the last note of each section (mens and ladies) and did a harmonic series which each fundamental.
So, for the males I did an harmonic series based in the lowest note of the bases of the ACJC Alumni choir (image 1)

And for the ladies I did an harmonic series based in the lowest note of the altos of the ACJC Alumni choir (image 2)
