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.

The quartonic family of temperaments tempers out the quartonic comma (monzo: [3 -18 11⟩, ratio: 390 625 000 / 387 420 489).

Quartonic

The name quartonic refers to the quartertone, since a somewhat flattened quartertone (representing the triptolemaic chromatic semitone, i.e. porcupine comma) is the generator of this temperament. The ploidacot for the temperament is omega-hendecacot, with eleven generator steps giving the perfect fourth. It is a member of the schismic–Mercator equivalence continuum, with equivalence number n = 11/2.

Overview to extensions

The second comma of the normal comma list defines which 7-limit family member we are looking at.

  • 1728/1715 or 4000/3969 gives septimal quartonic, with interpretation of the generator ~36/35. It also tempers out 4375/4374.
  • 10976/10935 gives yarman I (80 & 159) and slices the quartonic generator in three.
  • 5359375/5308416 gives yarman II (79 & 159) and slices the quartonic generator in three.
  • 2401/2400 gives tertiseptisix (27 & 212) with generator ~875/729, three of them give ~12/7, and four give ~250/243 with octave reduction.
  • 250047/250000 gives triquart (27 & 159) with 1/3-octave period.
  • 390625/388962 or 4802000/4782969 gives quartiquart (80 & 212) with 1/4-octave period.
  • 16875/16807 gives quintiquart (80 & 265) with 1/5-octave period.

Septimal quartonic

Septimal quartonic tempers out the orwellisma, the octagar comma, as well as the ragisma, and may be described as the 26 & 27 temperament.
