17th-octave temperaments

This is a list showing technical temperament data. For an explanation of what information is shown here, you may look at the technical data guide for regular temperaments.

Fractional-octave temperaments

---

← 16th-octave • 17th-octave • 18th-octave →

17edo is a "wheel" for some fractional-octave temperaments. The most notable relationship is the tempering out of the septendecima, the amount by which seventeen 25/24 chromatic semitones exceed an octave.

Gothic

The gothic temperament is associated with the 17-comma. It used to be known as septendecic.

Chlorine

The name of chlorine temperament comes from chlorine, the 17th element, and has no relation to the chlorisma.

Chlorine temperament has a period of 1/17 octave. It tempers out the septendecima, [-52 -17 34⟩, by which 17 chromatic semitones (25/24) exceed an octave. This temperament can be described as 289 & 323 temperament, which tempers out [-49 4 22 -3⟩ as well as the ragisma. Not only the semitwelfth, but also the ~5/4 can be used as a generator.
