Harmonics 11–22
The harmonic segment 11::22 (also harmonics 11–22) consists of harmonics 11 through 22 (11:12:…:22) and spans one octave above the root. Used as a scale, it is also called mode 11 of the harmonic series. The inverse consists of subharmonics 11–22. As 11 is a small odd number, this scale does not contain a perfect fifth above the root, although it does contain a 16/11 subfifth and a 17/11 ultrafifth / inframinor sixth.
