Harmonic series on G, partials 1–5 numbered Play.

The harmonic scale is a "super-just"

tuning tables are controlled by the left hand on the appropriate note on a one-octave keyboard.[1]

For example, if the harmonic scale is tuned to a fundamental of C, then harmonics 16–32 are as follows:

Notation Harmonics[2] Cents
C C C 16 0
C C17 D 17 104.96
D D D 18 203.91
E E19 E 19 297.51
E E E 20 386.31
F F7+ F 21 470.78
F F F 22 551.32
G G G 24 701.96
A A13 A 26 840.53
A A+ A 27 905.87
B B7 B 28 968.83
B B B 30 1088.27
C' C' C' 32 1200

Some harmonics are not included:[1] 23, 25, 29, & 31. The 21st is a natural seventh above G, but not a great interval above C, and the 27th is a just fifth above D. Play diatonic scale

It was invented by Wendy Carlos and used on three pieces on her album Beauty in the Beast (1986): Just Imaginings, That's Just It, and Yusae-Aisae. Versions of the scale have also been used by Ezra Sims, Franz Richter Herf and Gosheven.[3]

Number of notes

Though described by Carlos as containing "

notes per octave
.

Technically there should then be duplicates and thus 57 (= 78 − 21) pitches (21 = 6(6+1)/2). For example, a perfect fifth above G (D) is the major tone above C.
