Harmonics 37–74
The harmonic segment 37::74 (also harmonics 37–74) consists of harmonics 37 through 74 (37:38:…:74) and spans one octave above the root. Used as a scale, it is also called mode 37 of the harmonic series.
| Prime factorization | 37 (prime) |
| Dual sharp fifth | 56/37 (717.482c) |
| Dual flat fifth | 55/37 (686.288c) |
It is the first odd-numbered mode in which both fifths (all odd-numbered modes being either dual-fifth or fifthless) are diatonic, and has the incredibly accurate 44/37 quarter-octave.
